resolves #7316

Description

Running db-core integration tests requires thousands of file descriptors. This exceeds the soft limit on some OSes. For example, the default soft limit on file descriptors for recent versions of MacOS is only 256. The changes note the signs of the problem and how to work around it by increasing the limit. The ticket will be left open for the future investigation of why so many file descriptors are needed to run tests.
