In that exceptional case I suppose so. In the more general case the file system
can pass all work done to everyone. The parent could even be restarted and get
the work. If the work time is going to be significant it is smarter to write
the whole thing to expect a crash in the middle and pick up where it left off.

According to a test I just attempted, xterm doesn't do it. If you try to
paste a huge line (in my test case, "huge" turned out to be anything over
4095 bytes), while running a program that uses canonical input mode, the line
gets truncated and you get one bell for each character over the limit.

xterm just shovels the cut buffer data directly through the master device. It doesn't
try to break it into smaller chunks or deliniate the data in any way.
IIRC the OP, emacs was breaking the data into 500 byte chunks for some
reason. Why can't emacs just shovel the data in without any EOF characters

Too much in there to really comment on, but for starters
you don't check how many bytes are fetched by recv() in
your server code, nor do you null-terminate the comm_test
buffer before using it in calls to printf, strcat, etc.
As a quick-and-dirty hack you could memset your buffers

I can think of some scenarios. Imagine a case where the parent forks
off a bunch of child processes to do some work, expecting to get the
results back via return codes, pipes, or something else.
If the parent dies for whatever reason, it would make sense to kill the
child processes because any work they do won't be seen by anyone anymore.
