Absolutely. Just because the OS is generally real time and kernel priority doesn't mean that a user process can't use a semaphore. After all there are real time user processes and they need to signal or block each other. And user processes can get into a deadly embrace situation as well; it doesn't mean the computer is down, but the user processes are stuck and will have to be killed in order to get out of the deadly embrace.

What is semaphore in operating system?
Semaphores are devices used to help with synchronization. If multiple processes share a common resource, they need a way to be able to use that resource without disrupting each other. You want each process to be able to read from and write to that resource uninterrupted. A semaphore will either allow or disallow access to the resource, depending on how it is set up. One example setup would be a semaphore which allowed any number of processes to read from the resource, but only one could ever be in the process of writing to that resource at a time.

This is not always true, it depends on the operating system and the bootstrap process.
How is the execution context of a process used by the operating system?

What is process control block in operating system?
All of the information needed to keep track of a process when switching is kept in a data package called process control block.s A PCB is a data structure in the operating system kernel containing the information needed to manage a particular process. The PCB is the manifestation of a process in an operating system,
