possible radium issue

OK!!!  Progress.
So, if I'm reading this right, rasplit() seems to be ignoring the  
srcid on
some outputs?

Rasplit() does cache the output files, and tries to be smart about open
file descriptors, so its not reading a record, opening the output file,
writing a single record, and closing the file.  We keep a list of open
files per srcid, when the "$srcid" keywork is in the output filename.
It must be that we're confusing which file to use?

Does this seem to describe where we are?
