[M3devel] and sysutils waitpid

[Jay]

On a related note...C:\dev2\cm3.2\m3-libs\sysutils\src\POSIX has the waitpid(nohang)/sleep() loop that I had removed in other places, alas -- replaced in pthreads by waitpid(hang), whereas userthreads still has waitpid(nohang)/sleep (another flaw in user threads?)
 
and..isn't this a little odd:
 
    RETURN MIN(LAST(Process.ExitCode),LOOPHOLE(statusM3,Uexec.w_A));

If there are no users of this, I'll just comment it out.
