Method and apparatus for managing independent asynchronous I/O operations within a virtual machine

摘要

One embodiment of the present invention provides a system that facilitates performing independent asynchronous I/O operations within a platform-independent virtual machine. Upon encountering an I/O operation, a language thread within the system marshals parameters for the I/O operation into a parameter space located outside of an object heap of the platform-independent virtual machine. Next, the language thread causes an associated operating system thread (OS-thread) to perform the I/O operation, wherein the OS-thread accesses the parameters from the parameter space. In this way, the OS-thread does not access the parameters in the object heap directly while performing the I/O operation.
