If ELF header parametics can restrict VA (LA? I don't know the difference)
to have specified alignments to map dyn libs, taking 32KB is a good strategy
to go since the value will remove the possiblity where mmaped libs disagree
in VA indexing among processes.

I suppose page sharing beween KSEG2 and user space is also making
virtual alias.  Loading page from filesys results in VCEI or VCED.  Doh.
