Yeah. I think that strace provides this facility. I am investigating this.

Cheers.

Further to this, I've just tried ltrace and although it feels like it
should be "better" than strace, it doesn't seem to handle child processes
at all well (even with -f):

# Works, but ignores the child processes:
ltrace -e open,open64,opendir,fopen,fopen64,popen,SYS_open sh iceweasel

# Hangs (for me):
ltrace -f -e open,open64,opendir,fopen,fopen64,popen,SYS_open sh iceweasel


On the other hand, this does seem to work well, at the cost of
significantly more complex output:

strace -f -e open sh iceweasel

This problem is fixed in the current Unstable/Sid version, so I upgraded to
that version.
