Having said that, Parrot will allow time, memory, and IO quotas, with privilege based overrides, on individual interpreters. Assuming whatever firing off parrot sets those quotas. They certainly won't be on by default, as that's very much the wrong default, but it will be settable.
This probably won't help you, given the issue as described (since if your service provider's not even putting generic timeouts on spawned child CGI processes I expect there's little to no chance they'd configure things right), but the option will certainly be available.
