   The alternative (which seems cleaner) is to drive a state machine

I use this style myself.  A extra bonus is that it makes it easier to
build multithreaded applications (if this doesn't make sense to you,
think "internal multitasking" within an application), since nothing ever
blocks.

This does require a different style of structuring your code, but it
doesn't take too long to get the hang of it.  This is sometimes also
called "continuation-passing style".
