Comment:

 Guys, this isn't related to GHC at all. I ran it under {{{strace}}}, and
 it's obvious that either the application or the {{{http-enumerator}}}
 library is at fault. I see activities like this:

 {{{
 12306 recvfrom(17, "1000\r\n><div id=ghe"..., 32752, 0, NULL, NULL) = 1418
 12306 close(17)                         = 0

 12306 recvfrom(17,  <unfinished ...>

 12306 <... recvfrom resumed> 0x7fb0c64a0010, 4096, 0, 0, 0) = -1 EBADF
 (Bad file descriptor)
 }}}

 See what's happening there? Something is closing the file descriptor, then
 attempting to receive more data on it, and you're getting exactly the
 error you'd expect.
