Mathics currently misses some useful functions that allow to estimate the amount of RAM
available on the current machine and the memory usage. These are: MemoryAvailable, MemoryInUse, MaxMemoryUsed and $SystemMemory (apparently not documented, here is the output for my machine with 32 GB RAM. It basically just returns the total amount of RAM in bytes)
In[1]:= ?$SystemMemory
Out[1]= System`$SystemMemory
$SystemMemory = 32910770176
Attributes[$SystemMemory]={Locked, Protected}
This is somewhat relevant for #1174 although not critical.
