A signal handler can only be installed on the main thread, this was the reason why we could not use signals to profile multithreaded programs. This change installs the signal handler during sdk initialization which should happen on the main thread. The timers are still started on the individual threads to allow for profiles being recorded from different threads.

Just one question because I could not follow the logic there, but otherwise lgtm.
Can you also rebase master and resolve the conflict? Then we can
