Issue
Currently, if you try to create more than 128 named datasets, some
std::uint8_tvalues will overflow, and you'll end up overwriting other datasets with different names, and/or crashing.This change increases the limit to 512. Achieving this requires a few steps:
::ftok()only uses the lowest 8 bits from theidfield, so we need to use more than one lockfile name to differentiate unique keys.std::uint8_ttostd::uint16_tto hold the larger values.Tasklist
