Summary:
I encountered a 19s `hg sl` run where 13s were spent on
`remotenames.updateaccessedbookmarks` (8 times).
{F225347899}
The filesystem is unusually slow since the it's nearly full. However, the
updates are not really necessary since I'm not accessing more remote names.
Accessing one bookmark via smartlog rewrites the entire accessed file, which is
O(N^2) and undesirable.
Improve it by skipping writing if nothing has changed. In the future we might
want to optimize it further by:
- Only update (and do ui.log) "accessedbookmarks" at most once per command.
- Potentially drop the "accessedbookmarks" tracking by using "remotenames"
directly - everything in "remotenames" is accessed.
