At the moment, the netcdf-c library/dll is NOT
thread-safe at all. This is because it has internal
global state that might be modified by every thread.

A thread-safe version is under development, but will
not be ready for a couple of months. But note that
we will achieve thread-safe operation by using a global
lock so that all accesses to the library API are serialized.
This will mean that one can have multiple threads operating on
different files: read or write. But the IO will not be
parallelized.
