At least on MS-Windows, GDB tells me when a new thread is created.
So it does know.  I have no experience with threads on Posix
platforms, so I don't know for sure that the same is possible there.
But the "set print thread-events" command is not Windows-specific, so
I believe the above is also true for Posix platforms.
