PDMLWP (based on LWP) does indeed use the DJGPP signal mechanism for task
switching. If one thread spawns "command.com", threading safely stops
until command.com returns, due to the nature of signal handling under DJGPP.
AFAIK It's pretty much the only 'legal' way under DPMI to change
contexts in an asynchronous manner. I was forced to go to great lengths
and use nasty DPMI tricks in order to do it any other way.
