Without having read your patch too deeply, why not to use the
existing .lock file that can be found in the user configuration when LO
is running:

$ cat ~/.config/libreoffice/4-suse/.lock 
[Lockdata]
User=kendy
Host=eve
Stamp=804F9063F5450C58824E9DD1D3BB10C4
Time=Mon Mar 18 14:03:45 2013
IPCServer=true

It should be trivial to add PID=... line there, and check that one - how
does that sound?  See

desktop/source/deployment/misc/lockfile.cxx

for implementation of this mechanism.

Kendy
