I have reproduced the problem with a recent snapshot ('25), and strace, 
but I am only using a single strace output file, so it keeps going and 
over-writes the errored strace with the next run.  I will run it tonight 
while preserving all strace logs, but I can only run for about 1500 
iterations before I fill my disk.  I hope it happens before that.

Is there any way to tell strace to mimic the return code of it's 
inferior process?
