iOS optimization/bug/workaround. It seems that usleep(10) is paradoxically causing the background thread to hog a bunch of CPU on iOS. (I don't see this on Mac.) Increasing the time to about 60 seems to start helping. More so at 100, but I began to worry about sleeping to long. So instead I have an evil hack to change the thread priority for just iOS. (In theory, this approach can be applied to other platforms, but it is risky to muck with this.) Since SDL_thread doesn't have a priortiy API, I do some evil pointer math to get the pthread so I can call pthread_setschedparam. If SDL changes the implementation of SDL_thread including the structure layout, this will completely break.

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1329 * Playback immediately stops after the non-pow2 buffer

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1332 * The workaround is to always specify a power of two buffer size

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1341 * The HACK:
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1342 * If the buffer is short, try filling it up with 0's
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1343 * to meet the user requested buffer_size which

01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1345 * hopes to avoid a possible Loki bug with
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1346 * short buffers. If looping (which is the main
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1347 * reason for this), the negative side effect is
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1348 * that it may take longer for the loop to start
01e39f9f58d5 Bitkeeper era. Eric Wing <ewing . public \|-at-\| gmail . com> parents: diff changeset	1349 * because it must play dead silence. Or if the decoder
