[Ardour-Dev] Midi communications problems

[Quentin Harley]

Some feedback on this issue:

I added a small patch that takes away the segfaults, but fill the log 
window with messages - at least is is not crashing any more.  The 
problem definitely lies in the possibility of calling the routine twice 
at the same time, messing up the parameters sent to alsa.

Bug squashing time!
