Proper way to code multithreaded applications?

[Frank Benoit]

Hehe, this is no crash.
This is the garbage collector stopping all threads.
You need to configure GDB to ignore SIGUSR1 and SIGUSR2.

in GDB type
handle SIGUSR1 nostop noprint
handle SIGUSR2 nostop noprint

or make a startup skript or something like that.
