How long does a codec hang around and is it's memory freed when no
longer needed?

Perhaps one option is to create a memory pool style malloc
implementation so individual plugins could request a chunk of memory
as a pool (from the sample buffer?) which can then be used malloc
style within the plugin. When the plugin is done the whole pool can be
returned as one block to the sample buffer.

Perhaps this would provide a middle way solution to a global malloc
implementation and all the issues that raises?
