+  Log:
+  Well, here it is:  The checkin implementing robust recovery/retry and
+  asynchronous safe termination in plab allocation/deallocation/setup.
+  
+  Here are some of the more prominent changes/additions:
+  
+  * Bounded plab agent communication
+    Scripts should never hang waiting for plab xmlrpc commands to complete;
+    they have their own internal timeouts.  Node.create() in libplab is an
+    exception, but is always run under a timeout constraint in vnode_setup
+    and can be changed easily if the need arises.
+  
+  * Wrote functions in libplab to do the retry/recovery/timeout of remote
+    command exection.
+  
+  * Wrapped critical sections with a signal watcher.
+  
+  * Added code to handle various error conditions properly
+  
+  * Added a libtestbed function, TBForkCmd, which runs a given program in
+    a child process, and can optionally catch incoming SIGTERMs and terminate
+    the child (then exit itself).
+  
+  * Fixed up vnode_setup to batch the 'plabnode free' operation along with
+    a few other cleanups.  This should alleviate Jay's concern about how
+    long it used to take to teardown a plab expt.
+  
+  * Whacked plabmonitord into better shape; fixed a couple bugs, taught it how
+    to daemonize, and implemented a priority list for testing broken plab nodes.
+    This list causes new (as yet unseen) nodes to be tried first over ones that
+    have been tested already.
