[V4MD MAC] throwout and unregister

[Peter Salomon]

hi ruslan,

i´ll try o understand your intention of "trowout". let me repeat:

in local mode:
files are deleted from disk

in remote mode:
record of masterDB wich stores filename and filepath will be deleted
files remain on disk

> Because that db can be used by other users...

may be i do not understand - but it does not seem to make sense for me.
Other users (if they are in remote mode) cant use it, because its 
already registered out.
if they should use db again, simple db.close() seems enough...

does it make any sense to have dbfiles on disk which are not registered?
  if i need them open in local mode i simply open them, no?

you mean masterDB, right?

yes, i tried that already, but what if i have multiple databases under 
control of VServer?
And i want only ONE of them to be deleted...
I would need to register all the others again if i trash masterDB...
and also all users and passwords...

And lets imagine that VServer and also all the databases are running on 
a remote system, e.g. at a isp homingservice or somewhere else.
I have my admin rights and want to administer the db´s. If i call 
trowout, i want also the files to be deleted, no? otherwise i would 
call unregister...

i expected the function to do the same in local mode but also in remote 
mode.

now, where i read the code: do i need to call opensession first? i´ll 
give it a try...
