libb-cow-perl binary package in Ubuntu Focal armhf
B::COW provides some naive additional B helpers to check the COW status of
one SvPV.
.
A COWed SvPV is sharing its string (the PV) with other SvPVs. It's a (kind
of) Read Only C string, that would be Copied On Write (COW).
.
More than one SV can share the same PV, but when one PV need to alter it, it
would perform a copy of it, decrease the COWREFCNT counter.
.
One SV can then drop the COW flag when it's the only one holding a pointer to
the PV.
.
The COWREFCNT is stored at the end of the PV, after the "\0".
.
That value is limited to 255, after that a new PV would be created,
