pcmanfm as daemon

[farinet at arcor.de]

What's the purpose of that option to start pcmanfm as a daemon? To have 
automatically mounted external device etc?

I'm asking this since i'm underway to strip down furthermore lubuntu on 
a powerbook.

It started that i noticed problems moving windows around the screen (was 
extremely slow). So i tried with jwm (instead of openbox and other). In 
the end i sticked with openbox but without lxpanel (tint2 instead, which 
is eye candy ;) ). Using slim instead of lightdm and nitrogen instead of 
pcmanfm --desktop to set the wallpaper now i suceed to use, after boot, 
only 210Mb of ram (starting automatically xscreensaver, tint2, 
polipo+tor+vidalia,clipit, blueman,keepassx and thunderbird) which seems 
not that bad to me.

Moving windows is pretty snappy now. But i'd like to understand, if 
there is any disadvantage not starting pcmanfm in desktop mode. And/or 
for what it is good to start pcmanfm as a daemon.

Thanks a lot in advance.

Btw, with the help of tint2 launcher & openbox-menu, i have pretty much 
the same menu as by default in lubuntu
