Just in case anyone finds this in the archives in the future, I later discovered
that while I thought I was testing on a full T5140, that last test was actually
on a tiny sliver of an LDOM in it (4 out of 128 virtual cpus, 4 out of 32 gb
RAM).
After reconfiguring the system to assign all the resources to a single Solaris
instance (no ldoms), using the "after" version of the code that was integrated
to the X gate, the pkgdepend resolve step takes 1 minute, 42 seconds and the
full make_release_packages takes 27 minutes. (Most of which appears to be
pkglint off all the packages that were just built against the S11U1 /dev
reference repo, in a single process and thus leaving all the other cores
idle. Will have to look into speeding up that bit next.)
