My only concern is the
second case where I have myFunc1() whose return type is int, yet in the
prototype for ThreadDelayedRun() I'm making it look a whole lot like it's
void.
That isn't a problem at all.  boost::function is
specified to discard any return value.

The return type ultimately doesn't matter since this is specifically
designed to be a "fire and forget" system, which means that any return
value will be lost, there's no way for the invoking thread to recover it.
