+Any caveats?
+------------
+Oh yes, putting too many things into RamDisk might make the restoration that 
+happens when you login, a bit slow. But how many times do we login back anyway.
+
+In case you don't want things this way, you could make the rsync call that
+restores contents asynchronous by changing this -
+    $AS_USER $RSYNC "${SNAPSHOT_LOCATION}" "${DEST}"
+    into 
+    $AS_USER $RSYNC "${SNAPSHOT_LOCATION}" "${DEST}" &
+in src/helper.sh
+
+However in that case do not cache anything that would be needed as soon as you
+log in. And there is now way to figure out if rsync call got over, other than
+looking into Console.

 Uh, I assumed QuickSander's sweet app Cache2RAM [2] to be too sweet to retain
