Similar to the preceding commit, let's reuse the `compressed` array that
we use to store compressed data in. This results in a small reduction in
memory allocations when writing many refs.
Before:
HEAP SUMMARY:
in use at exit: 671,931 bytes in 151 blocks
total heap usage: 22,620,528 allocs, 22,620,377 frees, 1,245,549,984 bytes allocated
After:
HEAP SUMMARY:
in use at exit: 671,931 bytes in 151 blocks
total heap usage: 22,618,257 allocs, 22,618,106 frees, 1,236,351,528 bytes allocated
So while the reduction in allocations isn't really all that big, it's a
low hanging fruit and thus there isn't much of a reason not to pick it.
