Furthermore, upstream bash-completion developers are working on speeding
things up, by doing lazy loading (rather than loading all
program-specific completion handlers into memory at startup, they
trivially assign a global loader completion handler to all programs,
which then reassigns and runs the real loader for a given program the
first time you do tab-completion on that program); but it may require
support from bash 4.1 (I really need to find more time to get my bash
4.1 port to cygwin completed and posted).
