Signal handling problem in ruby

I presume I am running into similar problem but this time with ruby
1.8.6(2007-03-13 patchlevel 0) [i386-mswin32] (under windows).
Basically my program runs and spawns several threads, some of which
block on
network IO but the main thread after doing all initialization etc
installs a
signal handler by trap(“INT”) { s.stop } where stop() is a method
call to
stop processing.

The ^c signal is not delivered to the program until I send a network
(unblocks the different thread waiting for IO).

Is this issue seen by others on 1.8.6? Any pointers are appreciated.

Hi Nasir,

Make sure you trap the signal in the thread you put your main sleep,
otherwise maybe the thread finishes and the trap goes nirvana…
