Hi, I designed tracemalloc with Charles-François Natali in PEP 454. The API is a lightweight abstraction on top of the internal C structures used by the C _tracemalloc module which is designed to minimize the memory footprint.
I'm not aware of the pstats format. Adding a new tracemalloc.dump_pstats() function looks like a good idea. Does pstats allow to attach arbitrary data to a traceback? The root structure of tracemalloc is basically the tuple (size: int, traceback) (trace_t structure in C).
