I *think* it's meant to tell the compiler that a particular
template will be used by other units of compilation, so the
compiler/linker/whatever must ensure that the code is generated
for whatever instanciations are actually used. That will most
probably be both the compiler and linker. It may reduce compile
time, but I don't think this was the original goal, which (I
think, I tried googling it up, but most hits are to pages
saying "We don't support it") was more a hint to the compiler
that something would be used somewhere else, and to act
accordingly.
Now, it's all fuzzy memory that I have, I could be very wrong,
in which case I apologize in advance :)
