Well, for one thing, at the beginning of .bashrc and .bash_profile I put
a command like "echo start <thisfile>" and at the end I put a command
like "echo exit <thisfile>" where <thisfile> is the name of the containing
script and I never see the output from those echo commands. Here is the
output from the strace commands:
