Available() does not work on macos #33
Description
Available() delegates to TIocinq, which is stubbed out as a no-op.

Has anyone done evaluated what it would take to get it to work?
Seems like you might at least be able to do a select() call on the descriptor, to check if there's any data in the buffer (returning 1 or 0 would at least be marginally better than returning 0 all the time)
