Just some ideas. I don't know if either of these would help.
A long time ago, I wrote a single threaded application that had long
waits at various points. The user could "stack" operations during that
time but the code was written in such a way that it assumed that when
processing an event that it was based upon the current context. To work
around this we added fine grained timestamps to every event and any
event whose starting time preceded the end time of the last event was
In another app, we put up a busy cursor and blocked input at the start
of every event and restored the cursor and user input at it's end.
