GuestWriteWatchTrapReads takes all access to the pages of a range until
the resolver set with GuestWriteWatchSetReadTrapResolver has run for it.
A fault on a trapped page waits while the resolver runs on the watch's
own thread; host writes and GuestWriteWatchProtect run it first on the
calling thread. Collections keep trapped pages inaccessible, and
registering or unregistering memory drops its traps.

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.
A DWARF-mode index entry with no usable FDE, encoding 0, an unknown
personality, and a mode-3 immediate outside the function now fail the
unwind. A Linux test walks a synthetic __unwind_info blob.

The code that ends or replaces the process already includes Shutdown.hpp,
so LogFileFlush_nid_no_patch and LogFileRelease_nid_no_patch are declared
there instead of in LogFile.hpp, which only the log copy and its test
include.
The runtime writes its log to the process's standard output and error
through hundreds of direct stdio calls, so copying it into a file has to
work on the descriptors (POSIX) or handles (Windows) themselves.
Add the platform layer for that: opening the file for appending (relative
paths resolve against the working directory, the error text carries the
operating system error), pipes whose read end can be polled, keeping a
duplicate of the original standard stream, diverting a standard stream
into a pipe and putting it back only while it still is that pipe, and a
direct write to a standard stream for the crash reporters. Windows reads
the variable and the path as UTF-16. Nothing calls these yet.
Follow the console libc.prx (PPSA02530) at 0xcb2d0: ignore the argument and throw the static bad_array_new_length object. Star Wars Racer (PPSA28416) imports it.
nanosleep on macOS wakes about 25% late up to roughly 5 ms, then a
roughly constant 2 to 5 ms late for longer waits. Keeping 30% of the wait
as margin made a 100 ms wait spin about 25 ms. The margin is now 30% of the
wait, capped at 5 ms, so long waits spin at most about 5 ms.
