KDL while running git clone

[luroh]

hrev46712, gcc2, a two-CPU VBox machine running on an Intel CPU host. It seems reasonably easy to repeat here by git cloning the main Haiku repo. I hit it yesterday as well while doing the same thing.

I got a similar error with a 2 CPUs virtualbox machine, with, maybe, a simpler scenario : booting a hrev46706 nightly ISO image. I have posted a serial trace as part of a comment on bug #8345 https://dev.haiku-os.org/attachment/ticket/8345/port.2.txt.

A 4 CPUs virtual machine gave me a different error, closer to #8345.

Should be fixed in hrev46718. Please confirm.
