I think a better question would be, should we even bother with thread
wrappers? If we drop win32 support, we can just assume pthreads and
avoid a layer of indirection.
Yes, we would. qemu_thread_create ensures the newly-created thread
won't receive any signals, for example.
Some day the wrappers could even start using futexes directly if
there were a reason to do so.
For BeOS there once was a pthreads library project. Maybe the same
could work for Win32, implement the pthreads API and map to
corresponding Win32 API functions? Then QEMU could use pthreads API
and use wrappers only where strictly necessary. In theory this sounds
less invasive.
