What is an uninterruptible process?
...hard drive, or moving heads. During most of this time, the process will be sleeping, blocking on the hardware.
While the process is sleeping in the system call, it can receive a Unix asynchronous signal (say, SIGTERM), then the following happens:
The system calls exits prematurely, and is set up ...
