Regarding the use of signals and termination, I've been having
difficulty separating process termination (SIGTERM) from
Ctrl-Break (SIGBREAK).  If I register a signal handler for
Ctrl-Break and Ctrl-C using DosSetSigHandler, that process
receives termination requests (e.g. geneated by the End Task
button on the Task Manager), and these are marked to my
signal handler as being Ctrl-Break, not process termination.

This was happening under EE 1.2.  Haven't yet retested under 1.3.
