FreeOSMemory forces a garbage collection followed by an attempt to return as much memory to the operating system as possible.

PrintStack prints to standard error the stack trace returned by Stack.

ReadGCStats reads statistics about garbage collection into stats.

SetGCPercent sets the garbage collection target percentage: a collection is triggered when the ratio of freshly allocated data to live data remaining after the previous collection reaches this percentage.

SetMaxStack sets the maximum amount of memory that can be used by a single goroutine stack.
