Title:
  [regression] procps-3.2.8 top refuses zero delay input by s key

Status in The Linux Mint Distribution:
  Triaged
Status in “procps” package in Ubuntu:
  Fix Released

Bug description:
  top in procps-3.2.8 has a regression not present in procps-3.2.7.

  Pressing the 's' key while top is running, enables the delay in
  seconds or fractions of a second between updates to be entered.

  In procps-3.2.7 and earlier, it is possible to enter a delay of 0 to make updates go as fast as possible.
  In procps-3.2.8, top refuses to accept a delay of 0, saying "Not valid", but this is technically incorrect (see below) because a delay of 0 is as valid as any other non-negative value, and, in fact, procps-3.2.8 top happily accepts a delay of 0 if it is input using the -d command line option, i.e. "top -d 0".

  Top has always accepted a delay of 0. It's useful and top has been
  like that for over 20 years, and nobody has objected.
