[svn-r4948] Purpose:
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)
