SpiderMonkey takes a maxbytes option on a Runtime creation. It sets soft limit of memory usage, and when met SM just throws a specified exception. Current implementation of the js module just returns error 500 in this case.

Am going to try runing all the tests in VM with low memory boundaries. This will show us what is the SM made of ;)

Wow, good news! Do you need a maintainer for it or any other help?

We'll get four script engines perl, spidermonkey, v8 and lua, all in addition to one from the rewrite module and an opcode-driven machine from echo module. I love this!

Best regards,
Peter.
