Heh.... Rock and hard place... the old boomerang format was flat fields.  When 
we tried to use them for BLAST we couldn't read a field fast enought to even 
keep up because you have to read everything to read anything....  The BICEP 
experiment is using flat fields - with 100 detectors + aux fields - so to 
read 1 field is >100x slower for them than for a dirfile.  Of course they 
don't have problems with concurency :-)

What we are using now seems to more or less work, though I am not completely 
happy with our current solution, as I'm not sure that there is any promise 
from the OS that it will work (is there?).
