scePthreadMutexTimedlock on a mutex the caller holds, and
scePthreadRwlockTimedrdlock and scePthreadRwlockTimedwrlock on a rwlock
it holds for writing, returned EDEADLK at once. The console returns
ETIMEDOUT, as the prosper console oracle measured. They now sleep until
the timeout and return ETIMEDOUT, as FreeBSD libthr does. The POSIX
timed locks call these and change with them.

On a PS5 (firmware 13.60) the SCE mutex attribute calls return EINVAL
for a null or uninitialized attribute, scePthreadMutexattrSetprotocol
accepts 0 to 2, scePthreadMutexInit takes an uninitialized attribute as
the default one, and destroying a destroyed mutex returns EINVAL. Here
these threw, including for the priority protection protocol.
