Function disableDefaultSignalHandlers
Disables the signal handlers usually set up by vibe.d.
void disableDefaultSignalHandlers();
During the first call to runEventLoop, vibe.d usually sets up a set of
event handlers for SIGINT, SIGTERM and SIGPIPE. Since in some situations
this can be undesirable, this function can be called before the first
invocation of the event loop to avoid this.
Calling this function after runEventLoop will have no effect.
