#1 - GDB doesn't support having multiple target stack active, so you can only
debug multiple inferiors if they're all controlled by the same target.

#2 - The core target (corelow.c, mostly) doesn't support debugging multiple
cores.  E.g., core_bfd is a global.

The original report is about issuing "run" while debugging a core, which due to
the above would break.  As an intermediate step, GDB now pops the current
target from the stack, along with getting rid of all its inferiors, when you
switch to a ptrace-based target (IOW, core -> process).  Not ideal, but better
than breaking down.

Caused by the points above, mostly by #2 (core_bfd global).
