Well, "several years" is a bit of an overstatement.  It was accepted
in 2002.  It is still not on my host (I'm running Debian stable).
Initially there were some performance and correctness problems so I
wanted to hold off on it.  My understanding is that some performance
problems remain.

Anyway, Paolo Bonzini has made a similar suggestion and I've been
meaning to look into it in my spare time.  He's been making a
reasonable number of changes to the glibc regex code to get its
performance up to an acceptable level.  The most recent patch was
Nov. 23.  I was hoping for the dust to settle a bit before
incorporating the regex code into gnulib.
