Description
I am currently porting mimalloc to a new platform. When running it with my application I do get negative values for `current_commit` from `mi_process_info` after some time. It's a debug build so `MI_STAT` is set to 2. My port doesn't provide an implementation of `_mi_prim_process_info` so this is completely based on mimallocs own tracking.
I am working off of the latest tagged version `v2.1.7`.
Is this expected? If not is there anything known that could cause this and that I could look into?

Research direction
Start with mi_process_info and the internal tracking used when MI_STAT is set to 2; inspect how current_commit changes when _mi_prim_process_info has no platform implementation. Reproduce the negative value on mimalloc v2.1.7 and trace the accounting until you can determine whether it is expected or identify the tracking path that needs correction.
