Description of problem:
Using the Matahari Services agent, starting and stopping services always seems to result in a return code of 198.  On top of that, stopping a service occasionally results in a '$service dead but subsys locked'. 

Version-Release number of selected component (if applicable):
matahari-service-0.4.2-2.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.  install matahari broker and service agent
2.  start broker and service agent
3.  use qmf-tool or python to connect to service agent
4.  use qmf-tool or python to stop/start a service
5.  run status against service in a different shell
  
Actual results:
rc:198, maybe '$service dead but subsys locked' mesg on /etc/init/$service status output

Expected results:
service stopped or running depending on the method called with a return code of 0

Additional info:

# stopped service results in dead 
>>> cmd.getoutput("service crond status")
'crond (pid  1636) is running...'
>>> service.stop("crond",20)
OK (0) - {u'rc': 198}
>>> cmd.getoutput("service crond status")
'crond dead but subsys locked'
>>> 
>>> cmd.getoutput("service httpd status")
'httpd (pid  15737) is running...'
>>> service.stop("httpd",20)
OK (0) - {u'rc': 198}
>>> cmd.getoutput("service httpd status")
'httpd dead but subsys locked'

# even start comes back with a rc: 198 but it does seem to work, service shows running
>>> cmd.getoutput("service httpd status")
'httpd is stopped'
>>> service.start("httpd",20)
OK (0) - {u'rc': 198}
>>> cmd.getoutput("service httpd status")
'httpd (pid  22354) is running...'
>>> 

# more rc:198 but this time, no dead service msg
>>> service.stop("httpd",20)
OK (0) - {u'rc': 198}
>>> cmd.getoutput("service httpd status")
'httpd is stopped'
>>> service.start("httpd",20)
OK (0) - {u'rc': 198}
>>> cmd.getoutput("service httpd status")
'httpd (pid  22414) is running...'
>>> service.stop("httpd",20)
OK (0) - {u'rc': 198}
>>> cmd.getoutput("service httpd status")
'httpd is stopped'

# same result through qmf-tool
qmf: call 1 stop iwhd 20
