The difference is that after typing in the commands kill -SIGUSR2 [pid] kill -SIGUSR1 [pid] kill -SIGUSR2 [pid] kill -SIGUSR1 [pid] (in this order!) in another console, the program blocks under Cygwin while it exits normally under Linux. The last output under Cygwin is 'thread 2 waiting for SIGUSR2' while under Linux, one more line 'thread 2 received SIGUSR2' is printed out before the program exits.
