OpenSSL docs say, "Old documentation indicated a difference between 0
and -1, and that -1 was retryable. You should instead call
SSL_get_error() to find out if it's retryable."

Nsock poll engine: efficient use of pollfds array
...
Using socket descriptor as an index works okay for UNIX, though it
wastes the first several indices which are assigned to STDIN/STDOUT,
files, etc. However, for Windows it is really bad, since descriptors are
large, nonconsecutive numbers. Using a little overhead to track each
iod's index and the next empty space is worth it.

Fix handling of non-select()-able pcap handles
...
1. pcap_get_selectable_fd() may return -1 for some devices, even if the
platform as a whole supports select() on these handles. Check for
this condition throughout.
2. The various backend system calls (kevent, poll, epoll, etc.) do not
sleep for the timeout period if no valid handles are registered,
unlike select on UNIX. This leads to busy wait, looping continuously.
Instead, we call usleep() in those cases.
