Issue #755 has been updated by Roger Pack.


Note also that if you (re) set FD_SETSIZE=2048 after including winsock.h you can fit far more sockets in an FD_SET [in fact, it might fix the problem reported, as long as link against msvcrt6 sonce msvcrt seems to not allow more than 512 descriptors open at a time, anyway].
