2 suggestions:

1) Have an option to exec a program after rotating a logfile, with the first
   argument of the program being the name of the rotated logfile. This could
   be used for logfile parsing (e.g. 'logtail'). The logfile would have to
   be uncompressed at this stage of course.

2) For multiple logfiles belonging to the same process, does newsyslog end
   up HUP'ing the process for each log file? Perhaps, HUP'ing once would be
   better?

   [ Although having said that, most programs usually have their own log
     rotation program to rotate all the logfiles they generate ]
