Try to get this test to be more stable:
* disable gc during the test run because we are spawning objects and there
was an exception when calling Popen.__del__
* Always set an alarm handler so the process doesn't exit if the test fails
(should probably add assertions on the value of hndl_called in more places)
* Using a negative time causes Linux to treat it as zero, so disable that test.

Convert samples between 1-, 2- and 4-byte formats.
+ .. note::
+
+ In some audio formats, such as .WAV files, 16 and 32 bit samples are
+ signed, but 8 bit samples are unsigned. So when converting to 8 bit wide
+ samples for these formats, you need to also add 128 to the result::
+
+ new_frames = audioop.lin2lin(frames, old_width, 1)
+ new_frames = audioop.bias(new_frames, 1, 128)
+
+ The same, in reverse, has to be applied when converting from 8 to 16 or 32
+ bit width samples.
