[-- Attachment #1: Type: text/plain, Size: 211 bytes --]

Hello,

Ref: http://sources.redhat.com/gdb/bugs/1502
Turns out that the EBUSY error status value I was seeing is a Linux 
Kernel bug.  This KFAIL's that case.

baring problems, I'll commit in a few days

If it's a Linux kernel bug, that makes it an XFAIL, not a KFAIL.

Oops, yes (I had my Red Hat kernel, rather than FSF GDB glasses on).

Yo!  Copyright police!

I proof-read the rest of the patch and it looks stylin' to me.
gdb_test_multiple rocks.  The comment on the kfail is cool.
