[Bug libc/10354] New: posix_spawn should use vfork() in more cases than presently

["martinrb at google dot com" <sourceware-bugzilla at sourceware dot org>]

glibc posix_spawn uses vfork() in some cases, fork() in others.
Currently it is rather conservative in this regard.
For example, if there are any file actions, vfork() is avoided.
This restriction can be lifted, I think,
especially for the common case of closing file descriptors.
