I believe the current StrataFlash drivers actually sleep() for an
appropriate amount of time in both the write and erase routines. I'm
not sure that they are actually going to be wasting that much useful
bus time. I'm curious to know if you have any data to suggest this
bus usage has any significant impact on system performance.

No. I was just curious what you were thinking of. It could be done.
If you really think its worth it.
