Description of problem:

The fix for bug 152319 took do_mark() processing out of the
signal handler, but made it the last thing to do in the select()
loop, AFTER the test:
   if ( n_fds == 0 )
   {  ...
      continue;
   }
this means that do_mark() was hardly ever called .
Moving the do_mark processing before the ( n_fds == 0 ) in the
select() loop.

Version-Release number of selected component (if applicable):
sysklogd-1.4.1-28_FC4

How reproducible:
100%

Steps to Reproduce:
1. put -m N (N > 0) in /etc/sysconfig/syslog
 
Actual results:
MARK messages do not appear until a different message is logged.

Expected results:
MARK messages should appear every N seconds.
