MihawkOS (PPSA99170) reads sysctl {1, 14, 8, 0} while it starts and the
runtime throws on the unsupported MIB, which aborts the title.
KERN_PROC_PROC takes no pid, so the node lists the one guest process the
runtime hosts, as the same kinfo_proc kern.proc.pid already builds.

FreeBSD's mutex_lock_common tries the lock before mutex_lock_sleep
spins or yields, so a free mutex with yield loops and no spins was
yielding before its first try here.

Lock and timed lock now try the mutex up to the spin count with a pause
between tries, then up to the yield count with a yield before each try,
before they block, as FreeBSD 11.4's mutex_lock_sleep does. Trylock and
a lock the thread already holds do not spin. A uniprocessor host skips
the spins and keeps the yields.

Mapping a direct memory range that includes an unallocated physical
page threw std::invalid_argument and ended the process. It now returns
ENOMEM before anything is mapped, as shadPS4's MemoryManager::MapMemory
does.

KytyPS5 and shadPS4 return EFAULT for a null name. The test keeps that
and the rename and clear checks, and drops the null address, zero length
and past-the-end cases that no reference covers; the debt entry records
them as unknown, with the 32-byte name limit.

On Windows a sleep shorter than TimedWait's 0.5 ms lead, and the last 0.5 ms of a longer one, is a YieldProcessor spin in host code with no wait counted. A raise that found the target there could only be delivered through the return-address breakpoint or sampling, so sceKernelRaiseException at a thread looping on such sleeps was lost: a thread looping on sceKernelUsleep(200) lost the first raise in 5 of 5 runs.
The spins in SleepUntil and SleepNanosUnlessChanged now run under a DeliveryDeferral and drain APCs afterwards, as BeginPark and Unpark already do. A raise that finds the target spinning is queued as an APC and runs when the sleep ends.
GuestRaiseShortSleep raises 100 times each at a thread sleeping 100, 200 and 400 us in a loop, with sleep wakes on (SleepNanosUnlessChanged) and with APS5_NO_SLEEP_WAKE (SleepUntil). Both fail on main at the first or second raise.

Emscripten targets wasm64 without x86 assembly, Linux-only headers or the
x87 long double. These changes add __EMSCRIPTEN__ paths beside the host
ones; native builds compile the same code as before.
- libc: long doubles in guest varargs and scanf go through
GuestLongDouble, a plain copy where long double is the x87 format;
APS5_EXPORT emits no assembler alias; the guest arena is one aligned
allocation that zeroes pages when they are committed again; getifaddrs
keeps its link-level entries on Linux; /proc lookups and the host
stderr duplicate are left out.
- libkernel: file-backed mmap, EVFILT_VNODE watches, getcontext and
setcontext throw; getdents replaces the raw getdents64 syscall;
getdtablesize takes the resource limit alone.
- VideoOut leaves SDL, the display window and the HDR probe out,
Sysmodule asks libkernel for unwind information and Net includes
sys/time.h.
