Yes, that is true.  It will take time for the fix to work through the
system, and there is also the possibility of finding additional RC bugs
in the candidate version that further delay the cycle.  That's how the
iterative develop-test-release cycle works.

If that is indeed the case, no software would ever be released.

The trick is to make the number of known RC bugs at the time a package
moves from one stage to the next 0.  If a bug truly is release
critical, then that package should not be in the release while it
is known to contain that bug.
