We may not be so far apart.  1&2 are the reasons why I did not suggest
holding off on the 6.1 release.

OTOH 3 is why I think it important to use tools like Purify to create known
characteristics when possible.  When they find serious problems we should
provide fixes as soon as possible.

Well this is always true of hardware as well as software.  In NASA we have
a bit of a problem sending out a repair crew after a spacecraft is
launched, but we do sometimes launch things anyway.  Tom (I'm sure) and I
could both tell stories, but it gets a bit off topic.

Feasibility of a new signature is currently being evaluated.
