LzmaOutputStream leaks threads
When trying to performance test compression part, Hprof dump lists huge number of threads; it looks as if threads were leaked somehow. Since I am closing LzmaOutputStream there seems to be little I can do to prevent this, so it looks like a bug. (as far as I understand, threads are needed to work around impedance of underlying implementation which does not make it easy to model Java Input/OutputStreams; ideally this shouldn't be needed obviously).
Does your code properly close streams? Threads (should) terminate on close().
Test code definitely should have done that, but it has been a while. If that didnt occur, I would consider it a client problem not bug. So as far as I know this is not due to forgetting to close streams.
