From: Jason Venner <jason@idiom.com>
The posix regex library is VERY VERY slow.
I have a program that uses a large regex to parse some input.
I have a version in perl and a version in C++ using the freebsd posix
regex library.
The perl version is 100X faster that the C++ version.
gprof on the C++ version shows 99% of the spend in:
91.53 46.17 46.17 1152366 0.04 0.04 lstep
6.52 49.46 3.29 98497 0.03 0.47 lslow
