I didn't think that I realy have to mention this explicitly,
but ...  Of course it is limited by the total amount of
available memory (RAM + swap), and of course it is subject
to process resource limits (maxdsize etc.).

If you have a sufficient amount of memory and process
recource limits, it will work just fine.  Otherwise
it will break out of the loop.  Admittedly it should
print an error message in that case (easy to add).

A 3GB sequence of characters with no newline should be
quite uncommon.  I think the syslog protocol even has
a limit of 1024 characters per line, I think.
