Btw, while assessing the speed of running a 'man' command
synchronously, please be sure to do that with a man page that doesn't
have its formatted counterpart stored in man/catN.  Most
implementations of 'man' will store the formatted pages there, and use
them afterwards, thus avoiding the more expensive formatting command.
Displaying a pre-formatted man page is almost instantaneous, but
formatting a large and non-trivial page might be slower.

(The above doesn't mean to imply I object to the proposed change.)
