0.8.1 bug report
There's a loop somewhere in the directory index generation code, that causes
apache to go into a neverending loop sucking down memory until it exhausts
the system and core dumps. Here's a snippet of a backtrace on the stack:
#41 0x6e79 in process_request_internal (r=0xd99d34) at http_request.c:528
#42 0x7147 in internal_redirect (new_uri=0xd99d1c "/vrml.tech/vrml/index", r=0xd58f28) at http_request.c:606

This was in response to a request for
"http://vrml.wired.com/vrml.tech/vrml" (don't do it!) which doesn't exist.
however, a directory called "vrml.tech/vrml.art" exists. Here's the
output from ktrace:

Any thoughts? Not a big issue, but I did find a 16 meg core dump today :)
