Bug fix
Description:
    When a block was preempted from the chunk cache, it is possible that one
    of the pointers in the algorithm is invalidated and would generate a core
    dump.
Solution:
    Re-calculate the internal pointer and move the the preemption after the
    re-calc.
Platforms tested:
    FreeBSD 4.5 (sleipnir)
