Subject: [musl] Feature request: posix_spawnattr_setrlimit_np()

I have a program that raises its soft RLIMIT_NOFILE, but wants to
spawn processes with the original value (in case they use select(),
for example).  There seems to be no nice way to do this with
posix_spawn().  I can temporarily lower the rlimit in the parent, but
that interferes with other threads, and can make posix_spawn() fail
with EMFILE.

Corresponding glibc feature request:
