* OPFS VFS: add the opfs-unlock-asap=1 URI flag which tells the VFS to release ↵stephan2022-11-26
|\ | | | | | | | | implicit locks ASAP instead of during VFS idle time. This improves concurrency notably in the test app but brings a significant performance penalty in speedtest1 (roughly 4x slowdown).

| * Add an experimental OPFS VFS-specific URI flag, opfs-unlock-asap, which ↵stephan2022-11-23
