Ah, no. The really sensible thing to do would
be to wait only until all the blocking checks
are done (either just one of "too many", or
all other checks in the parallelization case).
Sleeping for a full second regardless of when
the blocking checks complete can waste time
between when the next plugin could run and
when it actually does. And with enough checks
introducing these extra arbitrary delays, the
overall latency for the full set of checks can
easily creep up.

Whether it would be simple to make that happen
in a particular software architecture is a
separate discussion; I'm just pointing out
the design issue here.
