Env memory leak

[xayam]

I tried to create an Environment many times using open_db and over time the RAM costs increased to the limit.

But if I alternate opening the Environment first for writing and then for reading, then the memory is freed and everything is fine

Affected Operating Systems

 Windows 11

Affected py-lmdb Version

lmdb 1.4.1

Do you have any example code?

Keep in mind that OSs are not very transparent at reporting mapped memory without using alternative tools. It will report mapped memory as in use where in reality is it just using up virtual memory space of the process, which is essentially free.
