What is the rationale for fread/fwrite taking size and count as arguments?
... one.
Consider this:
int intArray[10];
fwrite(intArray, sizeof(int), 10, fd);
If fwrite accepted number of bytes, you could write the following:
int intArray[10];
fwrite(intArray, sizeof(int)*10, fd);
But it is just inefficient. You will have sizeof(int) times more system calls.
Another poin...
How do I write a bash script to restart a process if it dies?
...use flock... in fact, the man page explicitly demonstrates how! exec {lock_fd}>/tmp/script.lock; flock -x "$lock_fd" is the bash equivalent to your Python, and leaves the lock held (so if you then exec a process, the lock will stay held until that process exits).

There is a better way to do this, and you've already discovered it: tee.
Only, instead of just using it for your stdout, h...

As pointed out by @c00000fd in the comments. Microsoft is changing this. And while many people don't use the latest version of their compiler I suspect this change makes this approach unquestionably bad. And while it's a fun exercise I would recommen...

How to redirect output of an entire shell script within the script itself?

For saving the original stdout and stderr you can use:
exec [fd number]<&1
exec [fd number]<&2
For example, the following code will print "walla1" and "walla2" to the log file (a.txt), "walla3" to stdout, "walla4" to stderr.
#!/bin/bash
exec 5<&1
