Detailed Description

Blocks asynchronous signal delivery on the current thread for the given signal.

This should normally be called before any secondary threads are started, so that all subsequent threads also have the signal blocked.

Warning:

This class is not thread-safe: the caller must use an external mutex or (more commonly) may only manipulate this class while a single thread is running.
