I don't understand this part. The read access is executed?

What!? Let me check I understand you correctly: You get an up to 120 seconds
pause when you use libcurl on this Fedora that you don't see if the same
program run on Windows or Solaris?

120 seconds is an insanely long time!

From what version did you upgrade? Do you only transfer plain HTTP? Have you
tried it on more than one specific Fedora host?

Can you tell us which of the example codes that shows this problem if you run
it against the yahoo http server? Are you using the example unmodified or can
you provide us with the code you're trying?
