Matt Jaffee e7f65cf7be implement global open file counter using syswrap ... close files after using them if global max is passed. I originally implemented this without the global count—just always closing files when done with them, and reopening for new writes. This was crazy slow for that one test that uses mustSetBits in a big loop. I modified the test to use importRoaring and everything worked better (though much more slowly). After adding the global counter, I ran the tests with that one test using mustSetBits again, and the performance was similar to master. After completing this PR, I ran the tests with the max limit set to 5—they still passed but were much slower.		2019-03-23 14:52:16 -05:00
