Macros are pretty gnarly especially when they aren't needed. This patch
replaces a few macros with static functions for synchronizing segment

this question is still mainly
dominated by the basic question of code quality. I'd rather move
something into the Linux kernel, enforce its code quality that way
a factor of 3).
However, what really kills Xen is that occasionally an undesirable
scheduling decision is made and the PIO latency jumps to an enormous
value. This ends making the mean PIO latency considerably worse than
the median latency.
