[Anthill-pro] old buildlife code on agent disk

[Buschmann, Peter D]

Our setup is that every workflow builds in its own directory:
[some]/[dir]/projects/[myproject]/[myworkflow].  For example:
projects/project1/build_trunk
projects/project1/build_branch1
projects/project2/build_trunk

This means that we always use a certain (more or less constant) amount
of disk space on this filesystem.  Of course, the amount grows as we add
workflows and projects, but the disk space used is independent of the
number of build lives.  This approach, though, allows us to minimize
repository checkout time, as each new build life needs only to update an
existing checkout rather than do a repository checkout from scratch.

After some time, development stops on, say, project1/branch1, and begins
on project1/branch2.  For a time, then, we'll have these working
directories:

projects/project1/build_trunk
projects/project1/build_branch1
projects/project1/build_branch2
projects/project2/build_trunk

But, per my earlier note, after 'x' number of days, we recognize that
project1/build_branch1 is no longer being used, and delete it.

Locking of the working directory is implicit (as long as each agent has
its own working directory filesystem), i.e. we do nothing special to
lock the working directory for the duration of the build.

Disk use on the server is a whole other question, and has a lot to do
with quantity of build lives and cleanup (inactivate, archive and
deletion) policies.

I think that we are going to move to this model. 

When you reuse the project-specific dir do you have to lock that
resource for the duration of the workflow?
