     That's why I push ex: Because a growing user base is the kind of
pressure that can make it get better and more comprehensive. Some
early courageous adopters are needed!

Noted :)  It would be excellent to see these three efforts congeal
into one but I believe that has already been wished for on this list
at least once before.  I like the idea of lposix but I find its strict
adherence to the spec somewhat limiting at times.  I like Ex's
approach for sleep() better than lposix'.  (With Ex, you can sleep a
fractional number of seconds whereas with lposix, you must sleep for
integral numbers of seconds.)  I do plan to check out Ex but I frankly
it is unfortunate that the development energy is not focused.
