This may not help. Signal processing thread must suspend main thread 
execution and switch it to signal handler routine. The only way to do it I 
see is the current method (originally designed by Steve Chamberlain, the 
inventor of gnu-win32 project): suspend the main thread execution, save 
current inctruction pointer, set it to signal handler address and resume 
main thread. Win95 may hang if context switching is while in a syscall. Why 
did it work before? Because all the signal mechanism was almost missing in 
cygwin.dll.
