With Ganesh’s approval, I’ve declared myself maintainer of the cgi 
library.  I uploaded two new versions.

3001.1.7.3 just fixes two regressions in 3001.1.7.2:
• Don’t use non-standard pattern guards.
• Restore compatibility with base-3 using extensible-exceptions.

3001.1.8 extends the API by adding a MonadCatchIO instance as I proposed.

(I’m going to hold off on formally deprecating throwCGI, catchCGI, tryCGI 
for now, pending some thinking about how best to reconcile the cgi API 
with Dan Knapp’s new direct-fastcgi API.)
