[svn-r11428] Purpose:
Bug fix.
Description:
In some racing condition, the process ID file might be removed just
the moment before timekeeper cats its content. When that happens,
the $pid is a blank. Timekeeper was not prepared for this.
Solution:
Added code to verify $pid is some number before proceeding.
Platforms tested:
Tested by hand only.
