The maximum cache size on Windows is determined by the largest
contiguous block of virtual address space that can be used to
memory map the AFSCache file.  On 32-bit Windows this value
will be something under 1.2GB.  It all depends on what third
party software is installed.  On 64-bit Windows this value is
effectively unlimited.
