Log Message:
Fixes for miscellaneous race conditions.  It's important to remember that
interacting with other processes is like working with threads, only much
worse, because they can do things even in the middle of executing C code!
So, even if we check right before a kill() or a pipe read/write, the other
process could still go away and the operation could fail.  Thus, all
interprocess communication operations must trap exceptions.
