It is legal to call this function in any thread. However, as this may block the caller, it should not be called from the Scheduler Thread.
Note
This function may induce IO or otherwise block the caller. If your code is running in the IO subsystem, the core will have already taken steps to ensure that blocking is acceptable. Otherwise, you should look at using the thread pool API to run a job in the IO pool.
