Is there an explanation on how multithreading in 7zip is implemented?
Does it compress several files in parallel, several blocks in parallel, or is the same block compressed by multiple threads?
And are there any trade-offs involving multithreading? For example, is the compressed file size affected?

Due to security requirements, I need to keep a log file of whenever any file on the system is read or written. The log file would look like this:
file - time - user
How would this be done?
See if auditd works for you - http://linux.die.net/man/8/auditd
You could also consider using inotify

How are treated constants in various languages/compilers? They take up space in RAM in runtime or are replaced with their values at compile time?
A compiler is free to go either way. The typical way to handle this is to use scalars directly while keeping larger objects like arrays in memory.
In addition, if you build an embedded system, they typically go into read-only memory like flash rather than RAM.

How many background workers can I use? Threads? etc.
Tha maximum number of threads you can create is only bounded by the resources that you have.
This could be the question asked in:
Maximum number of threads per
process in Linux?
What's the maximum number of threads
in Windows Server 2003?
Depends on your hardware/software configuration and your use cases.
