Also, these functions (if you dig into their implementation) are
documented as being for debuggers and/or GCs only. Specifically, they
can
not be used for synchronization, etc.
In 2.06 they were just:
/**
* Suspend execution of this thread.
*/
void pause()
{
if (state != TS.RUNNING || SuspendThread(hdl) == 0xFFFFFFFF)
error("cannot pause");
}
/**
* Resume execution of this thread.
*/
void resume()
{
if (state != TS.RUNNING || ResumeThread(hdl) == 0xFFFFFFFF)
error("cannot resume");
}
No prohibitions or warnings.
Okay, now follow SuspendThread and ResumeThread and you'll eventually run
into a (on windows) a function call which is documented on MSDN with a
bunch of warnings. Admittedly, I traced this a while ago, so pause and
resume might have been re-purposed away from GC use, but this used to be
the case.
