Could multiconfig replace a dozen serial instances of bitbake with a single parsing instance, or would it use a dozen parallel instances?  If the latter, is this a constraint in bitbake architecture, recipe DSL, or time/resources?

If the packages are the same and sstate cache would be used, then you
can build one on its own first to populate the cache and then build
the rest using the sstate.  Currently if the sstate isn't present at
startup bitbake schedules the same build twice, which obviously isn't
ideal but also *should* be fixable with enough effort.
