 Log Message:
 Pull up following revision(s) (requested by thorpej in ticket #113):
 
 	sys/dev/usb/ucom.c: revision 1.137
 
 In the HUP-wait path in ucomopen():
 - Use cv_timedwait() rather than cv_timedwait_sig(); the wait here is
  bounded (and fairly short besides) and seems appropriate to treat like
  other uninterruptible waits.  The behavior is now consistent with com(4)
  in this regard.
 - Map EWOULDBLOCK return from cv_timedwait() to 0, as the successful passage
  of time is not an error in this case.
 - If the HUP-wait time has passed, clear the HUP-wait timestamp.
 
 PR kern/57259 (although insufficient -- another change to vfs_syscalls.c
 is required)
