Monitors instantaneous memory pressure.
Samples /proc/meminfo every 29 ms and reports used memory as
MemTotal - MemAvailable, smoothed with a 30-second time constant. Although
memory is an alpha (hard) budget tracked from VM specs, the live figure is useful
for detecting actual pressure. Readings are Unit.Information.
