Re: Please vote: should we fix or drop the usleep() function?

Why breaking something already working (mostly)? I do not see Cygwin
or Linux is dropping usleep.

We could even leave it as it is, since it is no longer standard
(though fixing something is always good, esp. if it is easy). I guess
no one is actually checking the return value of usleep, anyway.

My 2 cents.
