Abstract: A method may include obtaining, for a thread executing application code, a recurring task, a recurring interval, a previous callback time, a starting counter value, and a counter trigger, initializing a current counter value to the starting counter value, and performing checks in response to adjustments to the current counter value. Each check may determine whether the respective adjusted current counter value satisfies the counter trigger. The method may further include in response to a check determining that the adjusted current counter value satisfies the counter trigger, invoking a callback handler with a callback that performs the recurring task, and in response to an elapsed time exceeding the recurring interval, executing, by the callback handler, the callback. The elapsed time may be an amount of time elapsed between the previous callback time and the first invocation. The method may further include modifying the starting counter value using the elapsed time.

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.
