Yes, lots:

commit and checkout are parallel at the file level

reconstructing revisions can be made parallel over windows on a large
file

hashing/compression/decompression can be done in pipeline with delta
generation / reconstruction

the wire protocol pipeline could run different parts of its stack on
different threads

diff generation can be parallelized at the file level

status can be parallelized at the directory level


..but in practice, there's not much in Mercurial that's heavily
CPU-bound.
