0x64, 0x66, 0x68, and 0x6a have all been reissued. Reissuing of
subspaces will become less common as the amount of disk space on
the master increases.
This information is not currently available anywhere.

When we're running out of blocks and a subspace has been sitting
idle for a month or so.

Yes, you are correct.

No, the proxies will generate random blocks from the random spaces.
If the master cannot generate any keys, it has enough in the queue
to last about ten minutes.

Eventually we will be able to. Getting the last one or two percent
out of a subspace requires a lot of cpu power and man hours

It's just a feature that's not currently available.
There are a couple of issues that make it complicated. I would
prefer it to be manual to avoid error on such an important
part of the project.
> How many people are in charge of the keyspace management? Who?
Several distributed.net admins discuss and plan keyspace management,
but for the most part, only one person actually changes subspaces
on the master. This is done to reduce possible confusion.

That, and the proxyinfo page, are the only pages on www.distributed.net
that are automatically generated very often.
The program that generates /graphs/ has to run some fairly intensive
programs on the keymaster for an extended period of time. Sometimes, for
a currently unknown reason, these programs abort. When this happens, the
script produces some nicely broken HTML. :)
The problem is currently being worked on. It should be getting better.
