For some reason, when opening a package loader right now in a 
reasonably fresh 3.7alpha-5764 image (in which a package loader has not 
been opened yet), I get the error stack below.  This is even after I 
deleted the "sm" directory, which normally works as a last resort.  
(Same thing happens in a 5707 image, after it installs SM2.)

Interestingly, if I look at SMSqueakMap>>saveCheckpoint: in the debug 
stack, the value of fname is ', :map.426.sgz' which doesn't look good. 
:)  If I look in the (newly generated) sm directory, the only file in 
there is map.376.sgz .
