I am attaching v3 of the patch which addresses the comments made
earlier by Bertrand about the comment in the patch [1]. Also I will stick with
vacuum_sleep as the name as the function will be inside vacuum.c. I am not
sure we should make this function available outside of vacuum, but I would like
to hear other thoughts.
Also, earlier in the thread, Alvaro mentions what happens
if the sleep time is 0 [2]. In that case, we do not do anything as we check
if sleep time is > 0 microseconds before proceeding with the sleep
