Thanks for the suggestion.  I've been thinking about it more, though, 
and I think it's more related to gwc than I first thought.

In particular, the playback cursor moves slightly with the burst of 
sound, then stops. I placed a debug line right after the calculation of 
bytes_left inside the play_a_block function in gwc.c:

bytes_left =
        set_playback_cursor_position(&audio_view, prev_cursor_millisec);
d_print("play_a_block: bytes_left %ld\n", bytes_left) ;  /* my addition */

And I get stdout like this:
Current stack limit: 10485760 bytes
press mx:235 my:179
play_a_block: bytes_left 87224
leaving start with audio_playback=1
play_a_block: bytes_left 71528
play_a_block: bytes_left 72296
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
play_a_block: bytes_left 63080
...

And it'll keep spewing this pretty much as long as I let it.  So it 
seems like gwc is failing to update the playback cursor position, and as 
a result not playing any more audio. I think I need to keep digging...
