It's hard to pick a default that will work for everyone. I can probably
see setting recursion limit somewhat lower than backtracking one,
though. Maybe 100,000/50,000 or something like that.

I would say that 100.000 recursions is too much. When I made my patch
it was segfaulting with such value. 50.000 is a much safer choice (at
least on my gentoo box, 8 MB of stack).

I made a patch (against HEAD currently only) that makes it possible
to set runtime limits on backtracking and recursion. It also
implements preg_last_error() that lets users check whether there was
an execution error (such as limit exceeded or bad UTF-8 or whatever).
Ilia, do you think it might make it into 5.1.3?
