I wish this wasn't true, but it was. When I say something is stable, I
mean that we have fixed every reported bug.

I have this hypothesis of software engineering which is that every order
of magnitude increase in the number of users finds as many bugs as the
previous order of magnitude increase.

With ReiserFS, I several times publicly said that it was stable, and for
that order of magnitude of users it was, and then the order of magnitude
changed and it wasn't....

With V4 we are going to benefit from an accumulation of testing scripts
(and more experience at what we do plus less hurried code), and that
will put us a few orders of magnitude farther ahead.

It will be a bit ironic that V4 is architected for greater data security
with its atomic filesystem operations, and yet V3 will for quite some
time offer greater data security in reality.

(V4 is currently being tuned for CPU consumption, and its VM
interaction. We have some fond hope of releasing in July.)
