 zynaddsubfx runs two threads.
 
 The main thread opens /dev/sequencer.
 The second thread reads from the open descriptor and blocks for input.
 The main thread tries to close the filedescriptor and stalls because
 the descriptor is in use.
 
 The sequencer device driver is buggy, the close should set sc_dying
 and wake up the pending read. So that's a kernel bug, not pkg.
