Comment:

 Here we have [https://github.com/macports/macports-ports/pull/10829 a pull
 request updating auto-multiple-choice-devel], a port with 554
 dependencies. It has taken 4 hours so far to attempt to install all
 dependencies. The Azure Pipelines build terminated after ~3.5 hours but
 its install-dependencies.log is already 1GB in size and contains 9669
 occurrences of "activate phase started at" which is wildly excessive.
 There should be 554 occurrences, one for each port, but for each of the
 554 we appear to be activating and deactivating that port and its
 dependencies, so many ports keep getting activated and deactivated over
 and over. Why? Can we stop doing that? This wears out build machine SSDs
 (all of the buildbot SSDs bought in 2016 died in 4-5 years) and wastes
 time.
