The state file is read an entry at a time, but what you noticed was 
related to the steps *before* state file creation: at bootstrap time, 
tailor needs to slurp the whole "cvs rlog" output and transform that 
into a collection of Changesets that it writes into the state file. From 
that point on, all operations should fetch a changeset at a time from 
the state file.

What it seems happening is that the *original* "cvs rlog" output stays 
around for more than needed... I'll try to understand what's going on.

Yup, this is really simple and effective: I implemented it in

Thank you,
