It might be good to use the subprocess module for individual conversion jobs for two reasons: * Each sub-process that ends will automatically free all memory again * You can launch several sub-processes to run in parallel on multi-core machines. Therefore you may gain some speed as well. This does of course not resolve the GC problems in their cause, but it should help, be a quick way out of it and additionally give the benefit of speed increases on today's rather more ubiquitous multi-core systems.
