Need to post more regularly... once I have posting from the plam sorted out.
Actually, just posting more regularly would be a big plus.
(Sounds like a good new year's resolution)

Plugins... Nearing completion. Yay! Quite a reasonably tidy server variables declarations and implementation now. Just one variable which I may eliminate and free (potentially a few kilobytes) as it is no longer strictly necessary.
Right now, only InnoDB has been modified to take advantage of it - easily make MyISAM make use of it for it's few variables.
Need to concider splitting out more subsystems so that more globals can be removed.
