Yes, mod_perl is what I'm talking about here (although you could do something similar in any persistent environment). You don't need to contact all processes at once -- you just need them to check for this when they do get a request. In other words, make all of your processes check at the beginning of any new request for a change in their environment and take action if they discover one.
