On hardware a load costs an open and a read of the file, plus about 1ms
and 30us per KB of loader work (pspautotests threads/scheduling/callcosts),
with the caller waiting throughout. It now charges sceIoOpen's and
sceIoRead's estimates for the file plus that, instead of a flat 500us.
Also notes why sceKernelLoadModuleByID fails from a game's own fd on ms0:
or host0: on hardware, which we don't emulate.
