But surely only in one of the example files (which unfortunately are
not marked as such, but the non-existance of a corresponding .o file
after a library build should give a good indication)?

The intension is that this should be possible, and it appears to work
in practice; but unfortunately there is a bug in the handling of
certain library-internal data structures that can cause some problems.
(I never noticed a problem while running my multi-threaded
application, but when reading the library source code I found that a
certain shared data structure can be used be multiple threads as if it
were private.)
