Comment(by mr-4):

 OK, just after an hour of moderate load I can confirm that the patch works
 - Tor doesn't fall over any more and is quite happy to serve floods of dns
 requests together with my bittorrent software, using the patched
 libevent2.

 Nick, I was very successful in cross-compiling libevent with, I am pleased
 to confirm, minimal effort (just applied my "standard" set of patches on
 the .spec file for cross compilation and it worked first time) - I was
 even able to optimise one or two things in the rpm build process on that
 package as well.

 The patch I attached in my last response above was, as it turned out,
 Fedora's attempt to deal with the multilib issue I highlighted to them
 more than 3 months ago.

 That patch is very crude and it does not work, but since this is in the
 rawhide repository I wouldn't get too worried about this - not yet! Hope
 they will be able to fix it before FC15 comes about. Though it baffles me
 why are they not adopting the approach I suggested to them...

 Anyway, tomorrow I intend to apply more solid loads on that machine and
 will post again. If everything is OK and everyone's happy this bug may be
 closed. Does everyone agree with this course of plan/action?
