+/* Tests the connection mayhem found by bug 695309 */
+
+// The full bug requires several things to fall into place:
+// 1. Cause the connections to timeout, while keeping them in the cache.
+// 2. Enqueue enough requests to cause things to be placed in the pending queue.
+// 3. Commands try to run but die instead.
+// 4. Enqueue more requests to open up new connections.
+// 5. When loading, the connection ends up pulling somebody from the queue and
+//    ends up treating the response for the prior command as the current
+//    response.
+// 6. This causes, in particular, GROUP to read the logon string as the response
+//    (where sprintf clears everything to 0), and AUTHINFO to think credentials
+//    are wrong. The bug's description is then caused by the next read seeing
+//    a large number of (not really) new messages.
+// For the purposes of this test, we read enough to see if the group command is
+// being misread or not, as it is complicated enough.
