Initiates garbage collection, even if manually disabled.
The full_mark keyword argument determines whether or not to perform a major garbage collection cycle. When set to true, a major garbage collection cycle is ran, meaning all objects are marked. When set to false, a minor garbage collection cycle is ran, meaning only young objects are marked.
The immediate_mark keyword argument determines whether or not to perform incremental marking. When set to true, marking is completed during the call to this method. When set to false, marking is performed in steps that is interleaved with future Ruby code execution, so marking might not be completed during this method call. Note that if full_mark is false then marking will always be immediate, regardless of the value of immediate_mark.
The immedate_sweep keyword argument determines whether or not to defer sweeping (using lazy sweep). When set to true, sweeping is performed in steps that is interleaved with future Ruby code execution, so sweeping might not be completed during this method call. When set to false, sweeping is completed during the call to this method.
Note: These keyword arguments are implementation and version dependent. They are not guaranteed to be future-compatible, and may be ignored if the underlying implementation does not support them.
