Storable dclone() is over 3x faster then Clone::clone() when used for creating
a deep copies of the big, complex data structures like MARC frameworks. See
also Bug 16044 comments #18 & #20.
This is a trivial version of Bug 16166. Performance test results (see Bug 16140
comment #23 for test setup description):
# master
146.29 (14.64+14.53+14.51+14.57+14.72+14.56+14.53+15.06+14.56+14.61)
# master + patch from this bug report
96.5 (9.77+9.63+9.77+9.77+9.68+9.05+9.68+9.83+9.63+9.69)
# master + Bug 16166
90.7 (9.15+9.10+9.16+8.41+9.19+9.19+9.11+9.19+9.02+9.18)
Bug 16166 is a bit faster and more comprehensive implementation, but also more
complex and harder to test/evaluate.
