* TODO:
* - test all options!
* - don't abort on lack of memory
* - Memory leak: in rare cases the proxy object is not freed (and there
* is a lot of data pointed from it)
* - Correct recapitalizetion of header names before giving the headers
* to curl.
* - curl does not close sockets when connection is closed and no
* new sockets are opened (they stay in CLOSE_WAIT)
* - add '/' when a user requests http://example.com . Now this is a bad
* request
* - curl returns 0 or 1 ms for timeout even when nothing will be done;
* thus the loop uses CPU for nothing
