Major slowdown in cp performance in 1.4 branch

[Brent A Nelson <brent@xxxxxxxxxxxx>]

A checkout today from the 1.4 branch seems to give terrible performance on 
"cp -a".  Something that took a little over 9 minutes from a checkout last 
week now takes over an hour (it hasn't finished yet).  CPU time consumed 
by glusterfs and all the glusterfsd processes is quite a bit smaller than 
it used to be; it looks like a recent patch is causing a substantial 
performance issue...

Thanks,

Brent
