> There is a race condition in disabling interrupts while closing resources.
> Currently this is guarded by a volatile variable, but there might be a race
> condition when:
> 1. interrupter thread first checked the shouldInterruptOnCancel flag
> 2. shouldInterruptOnCancel flag switched to false as Task/StreamTask entered
> cleaning up phase
> 3. interrupter issued an interrupt while Task/StreamTask are
> closing/releasing resources, potentially causing a memory leak
