> I'm open to experiment to use vfork() in _posixsubprocess
Are you going to do experiments? If not, I can try to do some in early January.

> Using vfork() can cause new issues: that's why there is a POSIX_SPAWN_USE_VFORK flag (the caller had to explicitly enable it). See also bpo-34663 the history of vfork in posix_spawn() in the glibc.

I've studied that, and that's what I referred to as "quality-of-implementation" problem. After glibc devs removed heap allocations and tweaked some other things, they could use vfork() in all cases. "musl" libc never had those problems and used vfork() from the beginning.
