__waitpid not a cancellation point

Subject: __waitpid not a cancellation point

Linuxthreads overrides waitpid but not __waitpid, so only the public name
is a cancellation point.  It also overrides system, so that is made a
cancellation point separately.  But it does not override popen/pclose,
so those use __waitpid with no cancellation wrapper inside or out.
Is this how it should be?
