   When I upgraded to 1.1 I noticed a strange error.
   The first time a client connects to the server the server sends the
   file without any problem.  It may do so on the next request as well,
   but ieventually the client receives a message saying unexpected network
   error and the request is not serviced.

This sounds like a symptom of a FPU-related bug that slipped into the
1.1 release.  I'll be making an `official' patch for this (and a few
other problems) RSN.  Meanwhile, the attached fix should solve the
problem for you.  Sorry for the inconvenience.
