    Ticket 50329 - Possible Security Issue: DOS due to ioblocktimeout not applying to TLS
    
    Bug Description:
    	A secure socket is configured in blocking mode. If an event
    	is detected on a secure socket a worker, tries to read the request.
    	The read can hang indefinitely if there is nothing to read.
    	As a consequence ioblocktimeout is not enforced when reading secure socket
    
    Fix Description:
    	The fix is specific to secure socket read.
    	Before reading it polls the socket for a read. The socket is poll
    	(with a 0.1s timeout) until read is possible or sum of poll timeout
    	is greater than ioblocktimeout.
