sounds not played (sometimes)

[ddyer0]

These is a problem with android sound clips, where "sometimes" a clip simply is not played, or is not played in its entirety, or is rendered as a nondescript "thunk" instead of correctly. Curiously, the problem seems to be more prevalent on newer and faster devices, and when the sound clips are shorter. The overall profile of this makes me suspect some interaction with the garbage collector or other memory management issues between codename1 and the underlying android vm.

The attached test problem plays an infinite loop of 1 second cheep-boop sounds. The actual sounds are much shorter than 1 second, and the timing is done with the clock so the rhythm ought to be very regular.
