Summary of Last Nights activities:

	1) Switched back to the GENERIC kernel.
	2) Edit /etc/sysctl.conf; added a line kern.maxfiles=5000
	3) Reboot
	4) Bump hard and soft proc.[mysqld_pid].rlimit.descriptors up to 2500.
	5) Bump hard and soft proc.[shell_pid].rlimit.descriptors up to 2500.
	6) Attempt to load the data, failure once again, same error message:

	"ERROR 1017 at line 445: Can't find file: './geeklog/userinfo.frm' (errno: 23)"

	7) fstat | wc -l shows 203 open files (done immediately following step 6 above.
	8) fstat | grep mysqld | wc -l shows mysqld only has 64 open files.
	9) The database only has 38 tables, and the datafile I'm trying to load is only
		37 KB.

Someone suggested a few days ago that perhaps the error reported is not accurate.  How would 
I test that?

My 'gut' says this is probably an easily resolved configuration issue, but I'm stumped on 
where to go next.
