[lvm-devel] [PATCH] clvmd: closedown the cluster after finishing of lvm_thread

[dongmao zhang]

when lvm_thread is processing remote request, the clvmd
received a SIG_TERM, it will free cluster resource before
the realwork of lvm_thread is done. If freeing the cluster
resource happens before send_message, it would cause the
remote command hangs forever.

this patch move closedown after the closing the working thread.
