should accept be protected with fport_wait_for_input?

[dskr]

Hi,

the fport fill input code provides a way to avoid some threaded  
deadlocks with fport_wait_for_input. I appreciate this tremendously!

Should this protection be extended to 'accept' in the socket code to  
prevent the entire runtime from blocking if a thread blocks on accept?

Cheers,
