I didn't realized it used the disk. Pipes could be used, so I'm curious why it uses the disk. (Ah yes, using pipes would prevent the parent from doing other work while the children are running. This is usually not a problem, but it would break P::FM's interface to support this.)

There won't be a race condition. It surely defends against that using the process id in the file name.

[choroba]: hmm... so you need something like bag from Test::Deep, but not for checking, but for generation
[Corion]: This has the dual use of easily requesting sequential URLs and also being suitable for testing
[Corion]: For testing, I want to skip all tests with the same value(s) once one test fails to cut down on the number of failing tests
[Corion]: choroba: Yes, in a way I
[Corion]: ... I'm treating the incoming value sets as bags... Maybe I'll just put the burden on the user, at least in the first attempt at a full API. generate( headers => [{ 'Content-Type' => 'text/plain' }, {'Content-Type' => 'text/json' ] ), even ...
[Corion]: ... if that is cumbersome for the caller to specify. On the other hand, maybe there isn't that big a need for permuting the header values
