[Swift-devel] coasters about half the jobs

[Mihael Hategan]

There was a bug in the block allocation scheme that would cause blocks
to be kept, in the long run, at about half of what would normally be
necessary. This included shutting down perfectly good blocks that could
be used for jobs. The effect was more dramatic when the maximum block
size was 1.

I committed a fix for this in the stable branch (cog r3052). If you've
experienced the above, you could give this a try. It would also be
helpful if you gave it a try anyway, just to check if things are going
ok.
