Yeah, I can imagine that a backlog of packaging activity does build up.
The thing I'm not entirely clear on is whether this is actually causing
some threads to get starved of work (and hence the total build time to
be longer than it needs to be) or whether we're really just shifting
things around in the timeline without making much/any difference to the
overall build duration.  (I'm not familiar enough with bitbake's
scheduler to know whether it will schedule tasks as early as possible,
or as late as possible, or something else.)

Just as a matter of interest, are you using qemu-based locale generation
or the cross localedef for your measurement?  14 minutes does sound like
an awfully long time and I wonder whether there is anything we could do
in absolute terms to just speed that process up.
