Hello there, I have ran into an issue with LMDB, which I can reproduce at will, but it seems a specific one. The git commit is 3368d1f5e243225cba4d730fba19ff600798ebe3 And this commit and my issue seems to be related.

1. I use MDB_NOTLS flag on environment open.
2. if I use MDB_NOSYNC flag for LMDB environment, the writer thread is stuck

after several transactions (writer thread backtrace):

P.S. tested against system provided lmdb version 0.9.14 and result is the same. So this maybe not related to latest commit in git.

If you're having this problem in 0.9.14 then it is certainly not related to 3368d1f5e243225cba4d730fba19ff600798ebe3.

You confirm that the issue does not occur in 0.9.13? Can you upload a test case demonstrating the problem?
