i have found that i never have the problem if the verbosity level in
libcurl is 0. if it is turned up to 1, then i get the hanging 9 times out
of 10. i wonder if both libcurl and squid are waiting a certain amount of
time after the post header for the body to come across, and sometimes one
vs the other 'wins' ?
