Actually that's what happens now under the covers.  This
occurs in a number of different places - each in its own way.
This can be factored out into a common singleton implementation.
Replacing this common one with a threadsafe version will
make the serialization truely threadsafe.

Then all you'll have to do is replace the trivial singleton
implemenation with your own which addresses you particular
situation.
