Description:
I'm gettin tons of lines like the following in dmesg:
TCP(ndbd:18299): Application bug, race in MSG_PEEK.

I'm running Gentoo x86_64. This bug occurs with the latest stable Gentoo kernel (2.6.29-gentoo-r5) as well as the previous stable 2.6.28-gentoo-r5. Theses errors started w/ 7.0.5 and persist through 7.0.6

How to repeat:
Just run ndbd under 2.6.28/29.

Not a (mysql) bug, but in fact a linux bug

They seem to only pop-up when ndbd is first launched and is starting up. Once started they stop.

According to 2.6.30 patch notes this is fixed. I'll wait for gentoo-source to hit portage and just ignore this till then. Thanks
