Thanks for your detailed report and I also read your bugzilla entry on this
issue.

What exactly is that command line doing HTTP-wise? Is it "just" asking for the
first 512 bytes from that URL? If so, shouldn't the plain curl command line
tool also repeat the problem if it was truly a pure libcurl problem? Any
chance you can try to write up a smallish more plain libcurl-using code that
can be used to attempt to repeat the problem?

Oh and btw, when it hangs, does it show it the resolver thread function as the
culprit in a gdb stack trace?
