Must MIDIRestart() be called from the main thread?

The subject says it all. I am trying to access the CoreMIDI library from LispWorks 4.4. Unfortunately I have found that calling MIDIRestart() (or any CoreMIDI function) interactively from a thread which isn't the initial thread results in the following:

CoreMIDI: timeout waiting for MIDIServer to start
-10839

If I build a LispWorks image which doesn't start multiple threads by default, calling MIDIRestart() does succeed. Once the connection to the MIDIServer is established it appears as if I can call CoreMIDI functions from any thread.

My question(s) are: Does the first CoreMIDI call have to be done from the main thread? If so is there any chance that this restriction could get lifted? Does anyone know how the initial handshake with the MIDIServer is done?

Thanks in advance for any insight/help.

Cheers,

-greg
