Isn't there an option that man-db grows a database cache while you are 
using it. Such that a page is added to the cache the first time you read 
a man page. Then you have a small extra delay only the first time. 
Usually people read only a small percentage of the man pages frequently. 
Caching all man pages is a bit excessive.

Man-db also displays non-cached man pages. What is the time difference 
between loading a cached or a non-cached page on Cygwin? Perhaps it's 
not worth caching.
