I noticed what I believe may be a handle leak against the latest (commit 7b9928c) on github, with the MDB_VL32 on Windows. After some poking around, it seems to be the file mapping handle, env->me_fmh. I threw it to a CloseHandle in the env_close0(…) and it seemed to resolve it.

Here’s a quick diff:
