I call the
MemoryInUse function, and it outputs about 256 Megabytes.
However, my activity monitor tells me Mathematica is using 5.45 GB and WolframKernel is using 2.32 GB.
Moreover, much more memory should be available than what
MemoryAvailable tells me is available on my 16 GB computer, taking into account the other tasks on my activity monitor which use little memory by comparison.
Why is this?
Perhaps Useful Info

$HistoryLengthwas set to 0 beforehand.
