	There are valid reasons to have multiple versions of perl
installed at the same time - the least of which is testing new
versions to make sure they work while still being able to build
and run things against older versions.

	So far as +threads being the default, that doesn't matter so
much to me, but I do want -threads available for anyone who wants
their perl to not have threads support (I recall something needed
a non-threaded perl, but that was awhile ago).
