I would be extremely suspicious of memory corruption with an fd that large;
it would indicate a kernel file table several tens of megabytes in size and
a minimum 10MB per-process file table associated with every process (on
Unix, but similar concerns probably apply on Windows).

(Also, I thought the new I/O manager didn't use select(), specifically
because it has annoying limitations like the above.)
