Package ‘foo’ would evaluate the value of ‘foo-tooltip-hide-delay’
which, by default, should yield the value ‘tooltip-hide-delay’ evaluates
to unless the user has customized ‘foo-tooltip-hide-delay’.  That value
should be passed by ‘foo’ to ‘x-show-tip’.  If you can think of a better
solution with less surprising results for the user please tell me.

As Eli expained elsewhere this is an internal value which, ideally, is
never used.  And I fully share everything Eli said on this subject.
