[Scons-dev] --cache-populate

[TOM TANNER (BLOOMBERG/ LONDON)]

appears to attempt to populate the cache twice.

At least, if I this and --cache-debug I get this:
CachePush(a.o):  1b497e11873e65dbbba9c70c07c0a993 already exists in cache
CachePush(a.o):  1b497e11873e65dbbba9c70c07c0a993 already exists in cache
CachePush(b.o):  ea507409fcca59ccde77147530e707ec already exists in cache
CachePush(b.o):  ea507409fcca59ccde77147530e707ec already exists in cache
CachePush(c.o):  274a89097b5da6c812cd54d4ea491f44 already exists in cache
