1. A computer implemented method, the computer having a processor, a block of virtual memory, and physical memory, comprises: obtaining, by the processor, the block of virtual memory for use in an emulated operating environment from a slab of virtual memory in a host environment executing the emulated operating environment; detecting a fill pattern of the block of virtual memory; maintaining, by the processor, a mapping between the block of virtual memory and the physical memory upon returning the block of virtual memory to the slab of virtual memory, wherein maintaining the mapping between the block of virtual memory and the physical memory is based, at least in part, on the fill pattern of the block of virtual memory; disabling local-timer interrupts; receiving an inter-processor communication instruction packet, wherein the step of obtaining is initiated after receipt of the inter-processor communication instruction packet; checking the inter-processor communication instruction packet for errors; and re-initializing the mapping between the block of virtual memory and the physical memory based, at least in part, on the fill pattern of the block of virtual memory.
