having run though some quick permutations here, MSVC_BATCH+CacheDir is 
not enough to trigger. It needs to add variantdirs - and it seems it 
needs there to be two-or-more variantdirs....

My outcome seems to have been a bit different than Steve's - when I 
switch to doing:

env1 = Environment(MSVC_BATCH=True)
env2 = Environment(MSVC_BATCH=True)

my tests fail on the rebuild of env1, and so doesn't even get to env2. 
And yes, at the point where I put a breakpoint, after the cache 
retrieval, shows the retrieved file indeed in place in the variantdir, 
but later it's missing.
