History
Ed Schouten 3a41ec6af7 Don't clobber td->td_retval[0] in proc_reap(). 
While writing tests for CloudABI, I noticed that close() on process
descriptors returns the process ID of the child process. This is
interesting, as close() is only allowed to return 0 or -1. It turns out
that we clobber td->td_retval[0] in proc_reap(), so that wait*()
properly returns the process ID.

Change proc_reap() to leave td->td_retval[0] alone. Set the return value
in kern_wait6() instead, by keeping track of the PID before we
(potentially) reap the process.
