There's a huge gap in the winealsa timer ticks:

(navigate directory)
(several "tick"s)
 22.374:0041:err:alsa:alsa_write_data tick
 22.385:0041:err:alsa:alsa_write_data tick
...
 22.569:0041:err:alsa:alsa_write_data tick

which causes an underrun and the audio glitches. The behavior was masked before
because we put a whole bunch of data into the ALSA buffer, which was enough to
bridge the large gap without an underrun.

There might be a problem with the timer code, but more likely we should be
using a more reliable method to trigger our write() function periodically.
