it was my goal to benchmark httpd ..but didn't get that far since it maxed
out the cpu and didn't let up...then i took out httpd......still did
that...and thats how i got to testing an entirely blank new stack.

must be a windows thing.....  i will be running it on digital ocean
ubuntu...so i',m not that concerned about a windows problem...but i would
still like to get to the bottom of it....will have to look into the tracing
tools. haven't had time today.
