Various technologies and techniques are disclosed for providing lazy kernel thread binding. User mode and kernel mode portions of thread scheduling are decoupled so that a particular user mode thread can be run on any one of multiple kernel mode threads. A dedicated backing thread is used whenever a user mode thread wants to perform an operation that could affect the kernel mode thread, such as a system call. For example, a notice is received that a particular user mode thread running on a particular kernel mode thread wants to make a system call. A dedicated backing thread that has been assigned to the particular user mode thread is woken. State is shuffled from the user mode thread to the dedicated backing thread using a state shuffling process. The particular kernel mode thread is put to sleep. The system call is executed using the dedicated backing thread.
A computer-readable medium having computer-executable instructions for causing a computer to perform steps comprising:
A method for using a dedicated backing thread for a system call for a user mode thread running on a kernel mode thread comprising the steps of:
A method for shuffling state from a user mode thread running on a kernel mode thread to a backing thread comprising the steps of:
