Certainly not in all systems, but I'll assume it's indeed the case here. 
There are certainly systems in which one of the reasons for copying is so 
that input from an I/O buffer (which might be fixed and reused) is copied 
to a fixed application buffer that is also reused. In such cases: lots of 
copying, no malloc or GC churn. I'd say this is very typical of Unix I/O, 
for example (granting that Unix doesn't do GC anyway).
