More accurately, the MTA is limited in its ability to apply
multi-threaded solutions to problems when the input bottleneck from
the qrunner is single-threaded.

Some of these problems can be addressed through improvements to
MTA configuration, but it certainly sounds like the ability to have
multiple qrunners going at the same time would allow the MTA a better
chance to maximize the potential overall mailing list throughput that
the server is capable of.
