The GET request adds a "www." to the connection address. Shouldn't
those addresses be the same? (In other words, the name in `url' should
start with "www." and the "www." should be removed from the format
string for `fprintf'.)

Unless your code goes into some all-memory-consuming loop, that's
clearly a bug in MzScheme. I'll see if I can reproduce the problem.

Meanwhile, you might want to use the "url.ss" libray in the "net"
collection, which provides an interface more like the Python one.
(Search for "url" in Help Desk for more information.)
