Reading the cachegrind data, it seems that of the 440k lock takes on writer
startup, some 190k of them (~40%) come from the store code: which it seems uses
some highly granular locking approach [ where a single-lock would be rather
better for our use-case ].

The attached patch fixes some part of this; but there are clearly many more
efficiency wins to be squeezed from the store code, more CRC verifiction to
remove eg.

The patch saves ~100k lock take/un-take pairs, and ~19m callgrind pseudo-cycles
(~1%) though we know locks cost substantially more than their pseudo-cycle 
weight.
