Revision: 1976

Author:   complement

Log Message:
-----------
Don't put closed sockets to worker_pool, if no data available

showmanyc (sockstream) check available data even for closed socket;

socksrv shouldn't push processor object associated with closed
socket and empty buffer to worker_pool---it can't receive data more.

If server and client both in the same process (sure?), server can
take signal on close client socket _before_ rest of data (tcp stack
implemenation dependent?). So sockios2_test::processor_core_income_data
may not read line. Check commented before clean this issue.
