What would you like to do?
Keep your current source file open in Xcode after a run completes (a.k.a don't die in main.m)
#! /bin/sh
# On alternate invocations, this script
# saves the path of the source file currently open in Xcode
# and restores the file at that path in Xcode.
#
# By setting Xcode (in Behaviors) to run this script when "Run Starts"
# and when "Run Completes", you can prevent it from switching to main.m
# when a run finishes.
# See http://stackoverflow.com/questions/7682277/xcode-4-2-jumps-to-main-m-every-time-after-stopping-simulator
# for a description of the problem and a bunch of solutions which don't work.
# We use the defaults system to save the source path.
# Change the domain to whatever you like.
DOMAIN="com.wearhere.keep_current_file_open"
KEY="savedSourcePath"
# The first time this script is invoked, this call will return a "does not exist" error.
# The second time this script it invoked, this call will return the saved source path.
# We copy stderr to stdout so that we can read both results using a single call.
savedSourcePath=`defaults read $DOMAIN $KEY 2>&1`
if [[ "$savedSourcePath" == *"does not exist"* ]]; then
# read path of current source file out of Xcode

For Xcode 4.2.1, at least, it seems that you can put ‘handle SIGKILL nostop noprint nopass’ into ~/.gdbinit (link). Even better!
