Instead of a registry key value would it not be better to dispatch a
message?

FWIW, (and INAH) I think you are correct about the threads vs. process
issue.  The fork/exec issue is solvable.  The switch to threads could
bring in all kinds of unforeseen issues.

Also, the performance penalty of processes is greatly overstated.
Postgres is not a web server and seeing the running processes in your
process manager has a lot of administrative benefits (the technical
issues of fork/exec notwithstanding).  You can see cpu load, run time,
kernel times, etc. without any extra software, just like in unix.
