Let me just inform you that we've been doing that in OpenERP tests: the 
buildstep (which is a single one) aquires a port from a pool of resources, and 
then feeds it to the build script.

v3/openerp_buildbot_master/bbot_oe/buildsteps/openerp.py#L226

And the re-usable class is defined in the 'openerp-libclient' project:
