I have seen several minute-long stalls due to either mounting or GC, but all processes that are not dependant on that partition keep running nicely. The only processes that suffer from such a thing are those that want to access the partition immediately, so mounting the root partition in rw-mode for example, is something to avoid because any given day GC can kick in right after mount, and then booting up can take veeery looong.
