I can confirm this.  One reason is that the server died and the client
doesn't handle this condition gracefully.

The other reason is a genuine bug in the client:  EAGAIN is not handled.

I only see this when the network connection is slow (or even has packet
loss).  Not a problem of crossfire IMHO.

I think there are two reasons for this:

a)  You've released the key, but the server doesn't know yet that you
have released the key because of network lag.

b)  I think it's possible that you get stuck in the "run" mode.  This
would be a bug in client or server.

Yes, client and server are now seperated.
