"Unix systems gladly replace system libraries that are in use"

Not really

usually you have the library abailable as:

liblibrary.so.1.2.3

and two symbolic links

liblibrary.so.1.2 -> liblibrary.so.1.2.3
liblibrary.so.1 -> liblibrary.so.1.2.3


What happens if someone "updates" on linux to liblibrary.so.1.2.4 ?

very simple: the old version is kept for programs which need the old one, and the symbolic links are reset to point to the new version.
And the new version has to be binary compatible with the old one, otherwise it would have to be a 2.0.0 release.
I experienced not one updating problem due to replaced libraries in 8 years of Linux usage. What happened was a mangled Kernel after a Kernel update (must have been too serious byte-flipping on the hardware or in the wire, because a re-download and reinstall cured the problem).
