I dont think its a bug in Chromium since the block occurs on the first 
call to recv() after select() reported the socket to be readable. That 
is crTCPIPRecv() calls select(), finds the socket to be readable and 
calls crTCPIPReceiveMessage() which blocks right away on the statement

if ( __tcpip_read_exact( sock, &len, sizeof(len)) <= 0 ).

So this really shouldn't block or should it?

It does happen with at least a couple of apps I tried, one of which is 
atlantis. I didn't test on other systems though.
