(2) Perhaps we need to be using the extern template feature to limit the
number of instantiations of various templates?
Template instantiations, via the typical "all-inline" nature of the
template declarations, have hidden visibility and should end up with one
copy per dynamic object.
But also with one copy per .o file, which presumably contributes to higher
resource demands for building. It's also a question if the linker is as good
at discarding duplicate debuginfo about templates.
I'm not sure whether there would be much
compile- or run-time benefit from using another strategy (plus, I'm not
sure whether it would work well across the various toolchains to give
template instantiations non-hidden visibility).
Given we have SAL_DLLPUBLIC_TEMPLATE, it seems likely that there shouldn't be
any big trouble there.
