Filesystem is quite expected to fail.

The classes were designed before exceptions were
fully accepted (I think) and would not be sucessful
if they didn't work on systems w/o exceptions.

-----------
Anyway:

shmem can use factory method returning
a objact acting like smart pointer. This would
hide the construction/initialisation phases
and work in exception-less environment.

For systems forced to live without heap this factory
method can take as parameter buffer
char[sizeof(shmem)] where the shmem
object gets instantiated.

Ability to provide "heap" for such systems
should be listed on "What I can do with shmem"
docs page.
