Duplicate simultaneous calls to same handler

It would be easy to tell. Start a counter in a local variable before one of the wait with messages statements, increment the counter by one, then after the wait with messages command put the counter into the message box, then subtract one from the counter. If it queues you should see counters going over 1. If not you will only ever see 1.

The user does something that calls the long handler while it is still running from a previous instance. Assume there is no flag in the script to prevent that.
