I'm sure it does.

My point is that flock in zsh must not reject timeouts between 0 and 1
microseconds. The right thing to do when a timeout falls between two
steps of granularity is to round up. When converting any kind of
floating point timeout/deadline to integers, it's also necessary to
round up, never down.
