Module Name:    src
Committed By:   mrg
Date:           Tue Feb 14 19:28:23 UTC 2012

Modified Files:
        src/sys/dev/usb: umidi.c umidivar.h

Log Message:
since we have to drop locks to call into the usb code, we need to make
sure that only one caller ends up doing something in close_out_jack().
add a "closing" member that is set when closing and error out in various
places.

with this in place i can read and write from umidi without triggering
any locking or other obvious issues, though the writing is currently
broken (it worked in 5.99.60-era.)  it runs the correct time, but no
output occurs no the synth itself.  more work needed here.
