Depends on D3359
Additions
- The PERL_PATH_TINY_NO_FLOCK environment variable has been added to allow users to disable file locking (and any associated warnings).
Changes
- Detection of unsupported 'flock' is no longer BSD-specific. This allows detecting and warning, for example, with the Luster filesystem on Linux.
Tests
- Improve reliability and diagnostics of tests run via 'do'.
- Protected t/locking.t from PERL_PATH_TINY_NO_FLOCK already in the environment.
