after zend_interrupt_function() callback VM continues execution using EG(cu=
rrent_execute_data).

callback may modify it in any way (e.g. unwind stack, or switch to another =
co-routine or continuation).


Thanks. Dmitry.

It seems that set EG(vm_interrupt) to 1 could not stop the vm execution but=
 only execute the interrupt_function and continue the current execution.

However, my RFC propose to stop the current execution.

Hi,

It should be possible do similar things using EG(vm_interrupt) and zend_int=
errupt_function() callback (introduced in php-7.1)
ext/pcntl implements asynchronous signal handling using this.

Thanks. Dmitry.
