This will not work under WIN32. "Signal" under WIN32 can handle the
"internal" exceptions only (like divide by zero) but can not catch
the external one (like ctrl-c). (Strictly say WIN32 has not "external"
signals at all)
To manage the external signal a special separate thread should be
created with its own event loop and the table of the "active"
signals and signal handles too.
In fact under UNIX this "thread " does exist as well. But it
belongs the OS process not user's one and user hasn't to create it
himself. Under WIN32 "if one wants some "UNIX-like" functionality
like signals one has to do this thread himself within his/her user's
code.
