Calling short-lived unix processes many times (note I didn't say where or when) might not be the right solution to most problems. (That's probably why I've never noticed this timing floor before.) But trust me, it is a real -- and actually sensible in context -- requirement here.

Server/client communication is unfortunately not possible in this case. Rewriting entirely in a language other than Haskell is possible, but not what I'd prefer given that the code is fairly complex (if fast).

Does anybody know more about what specifically is happening during these 150ms?

Thanks,
Tom
