fix

Setting connectionTimeout to -1 in server.xml causes each request to have high CPU 

java full version "1.6.0_51-b11-457"
Example:
<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="-1"
               redirectPort="8443" />

Everywhere I looked there seemed to be a if statement looking to see if it was below zero except in Http11Processor class. Attached is patch file. Which has resolved the issue on my server.

Thanks for the report and the patch.

This has been fixed in trunk and 7.0.x and will be included in 7.0.42 onwards.
