ExportedExternalMemory
class ExportedExternalMemory(val sourceContext: Context, val sourceMemoryIndex: Int = 0, val exportedName: String = "memory") : MemorySource(source)
Shared memory from sourceContext with index sourceMemoryIndex will be installed in the module and exported as exportedMemoryName.
Experimental hack, do not use. It is intended for using common shared memory across different GraalVM contexts, each created for its own thread.
