[Fresco-devel] client exit problems

hi

i found here are still exit-problems for clients... i will summarize the
behavior of the crashes...
i think it's not a bad idea to make the server more stable... even though
it sounds like _WORK_ and seems not to be a very lazy job... ;-)

if you not say "hey... don't change anything... we will remove this architecture/mechanism
soon..." i'll try to work on it...
 
ok... start...

1)
any time i kill the client by pressing the [X]-button the client crashes with
a assertion-error like:

omniORB: Assertion failed.  This indicates a bug in the application using
omniORB, or maybe in omniORB itself. e.g. using the ORB after it has
been shut down.
 file: current.cc
 line: 135
 info: !pd_callDescriptor
Killed

i don't know what this means...
<klugscheiss>my "internal sense" called to me: "maybe here are still CORBA-CALL's active" ...</klugscheiss>
but ... i'm new in CORBA... and don't really know what happens... ^^;;;;;

2)
after trying killing a client over and over again:
while true; do ./helloworld; sleep 2; done
*[X] pressing*
*wait*
*[X] pressing*
*wait*
*[X] pressing*
*wait*
*[X] pressing*
*wait*
*[X] pressing*
*wait*
*[X] pressing*
*wait*
...

sometimes this will crash the server... :-(

here is the stack-trace:
