* This code manages child processes. We can communicate with child
* processes using signals. Because signals are not supported on W32
* and Java (at least not nicely), we can alternatively use a pipe
* termination via signals, and not as a replacement for SIGKILL.
* Thus using pipes to communicate signals should only be enabled if
* the child is a Java process OR if we are on Windoze.
