David van Moolenbroek 29346ab043 PM: add support for wait4(2) 
This patch adds support for the wait4 system call, and with that the
wait3 call as well.  The implementation is absolutely minimal: only
user and system times of the exited child are returned (with all other
rusage fields left zero), and there is no support for tracers.  Still,
this should cover the main use cases of wait4.
