On a PSP, Init returns at once and a Create, Connect or Scan right after
it works (pspautotests net/adhoc/ctlinit). The login now runs on in the
background, and those requests wait for it, as they already did when it
was lost. The first login no longer resets the busy flag, which would
have cleared it for a request already waiting on it.
