Paging Google's Googlebot developers re. bugs

[Matthew Elvey <matthew () elvey com>]

Googlebot keeps ignoring my robots.txt file, thereby hammering the 
server and facilitating spam.

I think I found at least 2 bugs; see this thread in the robots.txt forum 
thread:
http://www.webmasterworld.com/forum93/782.htm

I've used Google's direct contact form last Wednesday; still no ack or 
response.

Please don't reply w/o reading the above thread, to avoid repetition.
I'm looking for a fix, not a workaround (such as a temporary total 
Googlebot ban).
