I think I'm going to investigate implementing a "listener" system with 
the midi input queues.... where various parts of the program add 
themselves as "listeners" to be notified when a message comes in. Seems 
like a better way than to have SysexGetDialog running a timer to poll 
the inport.

Also, what does everyone else think about JSL being able to receive a 
patch even when the SysexGetDialog isn't open? For example, if JSL is 
just sitting there, and you dump a patch from a synth, it could pop up a 
message saying "JSL just received a patch dump which looks like a Alesis 
DM5 Bank. Would you like to save it in your current library or discard 
it?". Then, all the SysexGetDialog class would need to do is arrange to 
send out dump requests (and notify the receiving mechanism that a 
certain type of patch is expected).
