Hello,

I have some question abouts the signal handling in 1.9.1 and haven't found =
any docs so I am asking here -=20
based on assumptions of course so please correct me if I am mistaken.

I am author of a window manager (subtle) and embed ruby as scripting langua=
ge. Since the switch from
1.8 to 1.9 I am facing many problems with asynchronous signals in multithre=
ading.

How is signal handling supposed to work and does the thread that ruby creat=
es automatically have any own
signal handlers? Due the asynchronous behaviour of signals like SIGINT the =
first thread with a handler will get
the signal and this is sometimes not my main thread.

Also when this ruby thread has any handler, can some signals be disabled or=
 should I just add traps and rely=20
fully on ruby and dispatch the signals to my main thread?

Thanks in advance.

Wbr, Christoph
