ATTENTION:
Just discovered that the above 101 konsole sessions limitation is manifested 
ONLY when the current bash-profile > Scrolling > Unlimited scrollback is being
selected for all the 101 sessions.

I disabled the scrollbar and was able to have the system Logout/Login with more
than the 100 konsole sessions (bypassing the 100 konsole sessions limitation).

I also tested by having the "scrollback set to Fixed number of lines: 50000"
and was able to overcome the session limitation of 100 maximum konsole
sessions.

I am updating the title of this bug. If having Unlimited scrollback is known to
force a limitation of 100 KDE konsole sessions, then KDE tester please close
this ticket.

NOTE: bug has been tested on many platform with Fedora F13. All platform do not
show any memory starvation. Systems were configured with enough systemic
resources: Multi-core CPU with 2GB, 8GB and 24GB of memory. Memory and CPU
usage showed to be OK. 

ALSO, previous version of KDE 4.1 installed with Fedora F10 showed a similar
symptom with konsoles session limitation (IN ADDITION THE CPU used to go to 99%
UTILIZATION on the struggling konsole trying to start /bin/bash) whenever
"bash-profile > Scrolling > Unlimited scrollback". With F13 with KDE 4.3 the
situation has changed as konsole hangs on the 101st konsole session without
causing the CPU starvation on trying to start /bin/bash.
