HAMMER - break atomicy for huge reads and writes.
* Allow reads or writes in excess of 100MB to be interrupted. Otherwise
it is a simple matter to DOS the machine into oblivion.
And if you think it could be bad on a 32 bit machine, just think what
can happen on a 64-bit machine with a multi-terrabyte address space!
