-----------------------------------
Sorry, I tried to mark it as invalid. I have already opened an issue on the correct project,
so this can just be removed.
> permit do_io_write after open_read to enable atomic overwrite of an existing object

> A number of more stateful protcols would benefit from the ability to atomically replace
an existing object.
> By adding the ability for non-HTTP protocols to retrieve a block of untyped header information
from the
> CacheVConnection and the ability to convert a read into a write (with an error if it
is overwritten by someone
> else) we can handle such protocols.
> Both of these ability are already present in the HTTP cache codepaths so generalizing
and exporting them
> seems logical.
