We could use a counter. After the first failure, do it once, after the
second twice and so on. And reset the counter as a higher order
allocation works. (just bound it somewhere)

So an exponential backoff, that might work.

As an idea I have created this patch as an addition to the original patch
in this series.

Would this be acceptable?

At the moment I have capped the value at 10, does anyone think it needs to
be much higher then that?

Hi,

I am working through mail backlog. If I may ask, has this patch proposal
had a result or does something need to be done still?

Hi,

I have not received any response to my additional patch yet.

Do you think I should submit it as a second RFC patchset?

Regards,
Jim
