Thanks for all the great responses! I changed my code so that each GUI handle is managed only by the thread that created it. This works perfect--and has eliminated all the crasing I was seeing!
As a follow-up question, how do you know *for sure* which modules are not thread-safe? For example, I wouldn't have guessed that DBI isn't thread safe.
