Very strange; the routines tmg_texmacs_time () and texmacs_time ()
only perform a system call and allocate no memory. Could it be that
Guile is responsable for the non-released memory? Notice that you
may use Tools -> Test -> Memory information to get some memory statistics,
when using fast allocation. You may also use the scheme command (gc)
to do explicit garbage collection.

When you say that tmg_texmacs_time generates small blocks of 16 bytes
which are not released, can you be more specific and tell which calls
to tm_new or new might be responsible?
