Detailed Description

Stores information about each system call number in form of SystemCall objects.

This is a caching map object. It doesn't fill in all system calls at once, but fills in each system call as it comes up in a lazy manner.

Each Tracee uses its dedicated SystemCallDB to avoid different tracees meddling with each other's system call state.
