sleep isn't required to support fractional seconds, so technically we
shouldn't use them. though i think the only system we target that
doesn't support them anyway is aix

we can use zselect if that's a concern. that's what i did in A08

(or we can implement sleep as a built-in. it's kind of surprising to me
that we never did that. ksh did)

as far as fixing this specific issue, though, would this be better?

  () { : > $1 } >( read; contextfn )

then the read is sure to hold it open until the anonymous function
manages to write to it. right?
