Fix curl-related crashes (sf.net #3386728)

Browse Source 
curl implements some of the timeouts using alarm(), where the alarm handler longjmp()s back into the
curl code. This is a bad idea in multi-threaded applications, since it is not guaranteed that
SIGALARM will be recieved by the correct thread. Therefore, we instruct curl to avoid using
signals.
