[ns] wireless examples segfaults with RealTime scheduler

[Shashi Guruprasad <shash@cs.utah.edu>]

I changed tcl/ex/wireless-mitf.tcl in ns2.1b7a allinone to use the
RealTime scheduler with the line

$ns_ use-scheduler RealTime

With the above line, ns segfaults. Hasn't NS ever been tested with this
combination? I've attached the output of gdb "where" if it is of any help.

I'm essentially trying to get emulation work with wireless scenarii.
