Throw a slightly more helpful exception when env variables
are partially populated. Prior to this change we'd get
a dictionary key exception somewhere later on.

Enable MBA/MBM tests if UMC (Unified Memory Controller) support is

The implementation always works on uintmax_t values.
This is inefficient when only 32bit are needed.
However for all functions this only happens for strtol() on 32bit
platforms.

The test produces multiple samples in a ring buffer, using a
