Generational GC exists to avoid that.  In most GC cycles, the stuff that
you copy is new and either is in use or gets collected at the next cycle.
Now and then you have a "major" GC that copies older objects.  Those
cycles are slower but there aren't that many of them.

If you actually profile an application, and GC is dominating the CPU
time, something is probably wrong with the program.  It's even that way
with GHC, which likely generates more garbage than typical Lisp programs
do, because of how the language works.
