If we intend this to be a permanent solution, the fact that PCRE probably doesn't handle wide strings is a problem.
If we intend it as just temporary speedup, we should be wary about allowing a wider set of regexp syntax, since we would have to allow the same set when a permanent solution is fixed in order to have backwards compatibility.
Other than that I can't think of any problems. After all, the API is pretty simlistic as it is.

Excellent! Now, what are the problems if we simply replaced the current regexp engine with PCRE? What problems do we face in the Pike API?
