truss issue

[Alexander Nedotsukov]

All,

I found current truss behaviour a bit strange. It coredumps always if 
trussed process do without any significant reason for my understanding. 
I also confused with comment for commit originally introduced this 
functionality 
http://www.freebsd.org/cgi/cvsweb.cgi/src/usr.bin/truss/main.c.diff?r1=1.9&r2=1.10. 
I propose patch attached to make truss always return result of trussed 
process and do not kill() itself. What do you think about it?

All the best,
Alexander.
