Andrew,

No, I don't think so but you do have to be careful. I use multiple event
loops in some of my programs and run into problems like the following...

Suppose I'm in a loop waiting, say, for the user to click 1 of several
buttons and he decides to relegate my program to the background, say, by
clicking in some other program's window. I process the deactivate event and
when I get the reactivate event how do I successfully re-enter the proper
loop. If they're both the same loop than I only have to maintain a state
variable to tell where to resume processing.

At any rate, these are the kinds of problems that can show up when you have
more than 1 event loop.
