Hi,

A while ago I wrote a sleep builtin mainly to test its impact in the boot 
process. The non-scientific results were not very impressive: around 1 
second.

So, I was cleaning up some directories and found the builtin. Instead of 
just nuking it, I'm forwarding it in case anyone wants to play with it or 
even merge it. If merged it will annoy those who are used to GNU's sleep(1) 
which supports the s/m/h/d suffixes, but not those using fractions as I added 
support for them.

Back then, I also payed attention to the resulting size of the binary, which 
obviously increased by a few KBs. However, I do remember that when switching 
from gcc 4.4 to 4.6 the resulting binary with the sleep builtin was smaller 
than the binary built with 4.4 and without sleep.

(interestingly, Debian's 0.5.7-3 dash is bigger than in 0.5.5.1-7)

Cheers,
