No.  This is post-fork (and had better remain so).  The change causes
the sub-postmaster that has just finished handling a cancel request
to exit with nonzero status, which the postmaster then interprets
(correctly) as a child process crash.

BTW, how are we going to do cancels in Windows-land?  The sub-postmaster
isn't gonna have access to the postmaster's list of child PIDs and
cancel keys ...
