Many Emacs commands and subsystems give periodic progress reports (xx%
of such-and-such processed).  These progress reports often slow down
processing significantly.  For instance, suppressing "Scanning file
..." in tags-loop-continue speeds things up a lot, even if the files
aren't yet read in.  In other cases (GNUS), the reports go by so fast
that you can't even read them.

A central routine could handle this better than the current ad-hoc
methods (parameterise by progress-report-interval, in seconds).  An
interrupt character is another possibility (cf.  Multics, Tenex).
Mix-ins to taste.
