Managing multiple isolated execution contexts in a single process

Abstract:

A method may include generating, for a host application, an image including an image heap including objects and a writeable object partition including a subset of the objects. The method may further include initializing, by executing the image in a process of a computer system, a first isolate including a first address space and a first read-only map of the image heap. The first read-only map may designate the writeable object partition of the image heap as copy-on-write. The method may further include initializing, by executing the image in the process, a second isolate including a second address space and a second read-only map of the image heap. The method may further include performing, in the first isolate and using the first read-only map, a first task that accesses an object, and performing, in the second isolate and using the second read-only map, a second task that accesses the object.
