FYI:

the process does not hang in an infinite loop. It just takes *very* long
:-( This bug is caused by bad implementation of the merging process of
snar files (files that store the metadata for incremental backups). When
a backup is about being removed other backups might get merged since
they depend on another. Every time this happens (and actually it happens
every time a backup is removed) the metadatas are merged. And now
consider two files containing metadata of 100.000 files that are merged
using a not so smart algorithm.

In fact, the problem of snapshot removal is much more complicated (in a
performance way) than it appears at first glance.
