Odd, I suspect you were doing more than just building a kernel, which
only takes a few minutes to build completely (even on a quota-enabled
machine ;)

It's just a left-over from the post-4.x SMP rewrite that didn't get
addressed until recently.  In the grand scheme of things quotas are
relatively infrequently used, so it was a higher priority for the
developers to work on other things first.  As I mentioned, fixing this
performance problem with quotas has now been completed in 7.0 and it
will probably make it back into 6.x before 6.3.
