[plt-scheme] Cannot check out the SVN (freezes/breaks)

I cannot check out the SVN for PLT. This seems to only happen for the
PLT project, and not any other subversion project that I have synched
from. I tried updating to the nearest libserf and subversion, to no
avail. (Well, technically this way I can use gdb to add in a goto that
enables subversion to cleanly error out). It seems quite odd though,
that I would be synching perfectly fine from the PLT SVN repository, and
then it would just kind of freeze up, never sending any more data when
it ought to just be piping it over.
