Solution 1

Because a critican section is only a critical section in the process in which it is defined.

Solution 2

Critical sections are thread specific: you don't need critical section across process boundaries.

Solution 3

Because Mutex can be used for that. They are less efficiency but can works across process.

Also, since the address space of 2 processes are different, a name is required to find the object in the other process and critical section are not named.
