Not so, or at least not so with the Linux-intel and Linux-alpha clients.
Just move the old "buff-in.rc5" to a new name, move the new
buff-in.whatever file to "buff-in.rc5" and the next time the client looks
for another block to process, it finds a whole pile of new blocks to do.
Granted, there is a tiny race condition where the client may look for a
new block while the files are being swapped. However, if done in a script
the swap will happen fast enough that it's a low probability of
In fact, I have a script running on the alpha box that watches for an
empty buff-in.rc5 file (the alpha client does not attempt to initiate a
fetch until it tries to retrieve a block from an empty file) and moves
another full buff-in file into place automatically. It sleeps with a
period of a few minutes less than the time the alpha takes per block, so
the lost time to perform the check is negligible.

An easy task at present assuming a proper OS that allows periodic
background script execution.

Again, can be implemented right now with those scripts I keep mentioning.
Plus, all three ideas can be done without one change at all to the
existing client source code.
