Guest descriptors are host descriptors, so a guest that moves standard
error with dup2 also moves the stream sceKernelDebugOutText writes to. A
title that forwards its standard error to the kernel log through a pipe
then reads its own debug output back and logs it again without end. Before
the guest's first dup2 onto descriptor 2, the host's standard error is kept,
and sceKernelDebugOutText writes there.
