As part of reviewing a patch for adding assertions to
pa_memblockq_push() calls where safe, I'm investigating whether it's
safe to assert that the pa_memblockq_push() calls in module-echo-cancel
always succeed. During that investigation I've noticed some unrelated
problems in the echo-cancel code, resulting in these patches. I have not
tested the patches (testing them would probably be rather tricky). I did
ask Arun about this sample dropping patch before preparing it, though,
and it looked like a bug to him also.

Asking for testing is good, but sometimes testing just too hard to do,
and leaving a likely bug unfixed doesn't sound like a good idea.
