IOSchedulerJob.sendToMainloopAsync

Used from an I/O job to send a callback to be run asynchronously in the thread that the job was started from. The callback will be run when the main loop is available, but at that time the I/O job might have finished. The return value from the callback is ignored.

Note that if you are passing the user_data from [gio.global.ioSchedulerPushJob] on to this function you have to ensure that it is not freed before func is called, either by passing null as notify to [gio.global.ioSchedulerPushJob] or by using refcounting for user_data.
