#364 playmode not exiting properly

[Anonymous]

while in playmode
tracks play fine, but upon hitting stop, grip
proceeds to cycle through the tracks (without
actually playing them) forever until restarted

skimming through an strace it appears to be
polling even when polling is turned off. after
stopping playmode there are subsequent read()'s
returning resource temporarily unavailable
