You won't notice much difference in times (time it and see for yourself!).
On my system, the difference is about 1.6 seconds (5.26 verses 6.75).
Considering that the disk cache makes a difference of 3+ seconds
(9.96 -> 6.75), it just isn't a big deal. It is reasonable for
makewhatis to drain the entire contents of the man page fed to it
from whatever source, whether it uses the entire input or not. Trying
to 'fix' the size of the pipe to avoid the problem isn't a good solution.
