Sanjay,

As I said, it's determined by strace and Linux kernel version. I never said strace would kill the traced process. On the box I'm primarily concerned with, CTRL-C sends a SIGSTOP signal to the traced process. This signal freezes the process without killing it. You can try
sleep 10 &
strace -p $!
CTRL-C
Will the sleep ever end? What's your strace and Linux kernel version?
