The most significant problem I'm dealing with now has to do with a
failing bproc_move() to an Interlagos server. When the bproc kernel
module on the Interlagos target node returns to user space, the
process suffers a rather immediate segfault. This works on
non-Interlagos. This also works when doing a bproc_move() *from* an
Interlagos node to another non-Interlagos node. The failure just
occurs when the target node is Interlagos.
A bpsh of a binary image to an Interlagos node works. The difference
between bpsh and bproc_move() is that the bproc_move'd process has
already begun to execute. Its libraries are loaded. Versus the bpsh
case, where the program's memory image is still rather pristine.
