Detailed Description

Class implementing mechanics of conversion of signals to exceptions.

Each instance of it stores data for jump placement, thread id, and callbacks to be called during jump (for proper resource release).

The active handlers are stored in the global stack, which is used to find appropriate handler when signal is raised.
