I'm not sure it solves your problem (haven't tried the example), but just looking at the code there is clearly a performance bug: the pattern is passed to Pcre.pmatch "on the fly" using label "~pat". This is ok and convenient if it is used only once, but is bad if it happens in a loop. Precompile the regular expression outside of the loop (let rex = Pcre.regexp "...") and pass it in with label "~rex" to solve this problem.
