Aha - I found something. When I first ran the touch command above, I
stopped at about 8000 files (or about 400k for the subsequent echo command
line), which gave the nice "Argument list too long" error. But when I
increased the number of files to 45000 (or about 2 meg of command line),
the same command failed with a segfault with bash 3.0, and gave no input
but left $? at 5 (matching EIO) on the alpha bash 3.1. I will have to try
debugging it now, but it seems odd that exec() is dying with E2BIG in one
case and EIO when the input is even bigger.
