The size of the stack cache.
This variable determines the maximum size of the stack cache.
When a process dies, its stack is put in the stack cache for future reuse if there are currently less than
stacks in the cache.
Increasing the value of this variable allows more process stacks to be cached and reused.
Note that stacks are allocated in generation 2, hence a program with a high turnover of processes may need to call
periodically unless all the stacks of dead processes are reused.
