Sorry for the confusion. The version that has the space leak is the
version that I included with my initial mail and doesn't increment
the sequence number. Once thee space leak is fixed I will need to add
code to increment the sequence number (not yet implemented). I tried to
make a minimal version that reproduces the problem, but I need to be
able to update the state in the "real" version.
