… the exception message to stderr. Fixes other.test_warn_undefined on Windows, which would fail if Python spawned node.js in the case where it printed stderr and terminated to an uncaught exception, leaving unflushed data to stderr, and not all unresolved symbol errors were printed to console. Node.js stderr does not have a flush() mechanism, so must gracefully terminate the execution instead.

…to allow user code to configure how many SDL audio buffers to keep simultaneously queued up for the audio backend. More buffers means less change of starving (and cracking audio), but increases latency. Fewer buffers lower the latency at the risk of playback glitches. Make minimum audio buffer size 128, which should be way below anything reasonable already. Clean up commented out code.
