* Would you like to delete double underscores from these variable names?

* I find another implementation detail suspicious.
Should the parameters âsleep_usâ and âtimeout_usâ be enclosed by
additional parentheses (similar to four other macro arguments)?

* Can the tag âFixesâ be relevant also for such adjustments?
