After digging into the problem some it appears that vista handles select
differently from XP and the libcurl code doesn't account for this. On
XP when a socket is disconnected select returns with that socket it the
FD_SET as being changed. This is the behavior curl expects, on vista
however the select call just times out. This timeout causes the library
to go into an infinite loop as there is no "MAX_TIMEOUTS" check. It
seems this is something that should be addressed...
