that's a thrilling question, but i don't think your approach will work. because in principle it is not possible to share object references between threads. all shared data must be scalars. so maybe you're trying to catch the problem at the wrong end? if i understand you right, your main thread needs to know whether a child thread (one of the brains) closed the connection. the first idea that comes into my mind is: reverse the socket architecture. let the main thread listen and accept connections, not the brains. if this is a trivial proposal to you, there's maybe another thing possible, namely via localizing a hook for $SIG{__DIE__}. when a brain's socket closes the connection, this should be noticed. and the $SIG{__DIE__} handler should then put maybe the brain's identifier on a thread queue, which now effects the main thread to re-establish the connection.

i don't know ehether these remarks will be helpful, they just came into my mind.
