Snippet #597

Just tried running Walrus under JRuby, for kicks, to see how performance is with batch-processing a large number of templates using walrus fill; unsurprisingly, it rips through them very quickly and memory usage is relatively low despite the memoization employed by the packrat parser. MRI, on the other hand, suffers from crippling memory bloat under this kind of workload; you either exhaust all memory on the system (because it doesn’t get Garbage Collected even though it should) and your machines slows to a halt and the run never ends, or you CTRL-C the process.
