A weird dns bug

[Petr Janda <elekktretterr@xxxxxxxxxxxxxx>]

There are 2 hosts:

devel.a.xxx.com
devel.b.xxx.com

the actual host names are "devel.a" and "devel.b".

when you resolve "devel.a" to an IP, "devel.b" doesn't resolve. Then I 
log onto the "recursive resolver" and rndc flush, then i can resolve 
"devel.b" but "devel.a" doesnt resolve untill i do rndc flush again.

Whats going on?
