Is anything lost by going to POSIX threads in GCC?
Maintaining our own specific glue? :)
Yes. The threading support in gcc is designed around POSIX and when
enabled gcc directly accesses the calls. No extra overhead calling an

This isn't a GCC issue.
The overhead I am referring to is (was?) in RTEMS: Basically everything,
which is conditionally built with --enable-posix in RTEMS.
