I suggested something similar in 1997:
http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/1997-02/msg00229.html
The message proposed a tasking package that would dispatch atomic
chunks of code. I eventually wrote one in Perl; it's on the CPAN as
POE. In the Perl version, code atoms are just carefully coded subs.
They would be basic blocks in a bytecode dispatcher.
I still like the idea, so a few months ago I wrote a prototype of it
in C for perl6-internals to tinker with. It's called "phat", there is
some discussion about it in the list archive, and the working
prototype (for prototypical values of "working") is still at
<http://poe.perl.org/phat/phat.c>.
