This is one of several approaches, any of which -- or none of
which -- might be suitable for you.

What drives your need for this behaviour?  The answer
will determine the best approach.

Define "immediately".  In answering please consider issues such
as threads that are blocked in kernel calls, such as receiving
data on a socket, as well as data integrity issues (e.g. what happens
if by "immediately" you mean "at the end of the current bytecode
instruction", and if that implies that you may have system
data structures that are corrupted?).

Searching the list/newsgroup archives with Google will reveal
past discussions and possibly some useful responses.
