Thanks for looking.

I actually went a bit farther down this path on my branch, adding:

    0249cca turn remote into a to_xclose target
    84e2677 turn linux-thread-db into a to_xclose target
    9fdaa64 fix exec_close to be multi-target-aware
    7fd03ff introduce the target stack
    698a56f convert current_target to be a pointer
    68520c8 convert exec target to to_xclose

These are all things pulled over from the mostly-defunct multi-target
branch.

I probably wouldn't be inclined to put these -- or maybe even the bulk
of the "baby step" series -- in right now.  They aren't really that
useful until some other things are finished, like adding the target ID
to ptid.

However, it's probably useful as a starting point for the next attempt
at multi-target.  In particular it's much less invasive than the earlier
approach, and the "convert current_target to be a pointer" patch (the
biggest one) was mostly done with a perl one-liner.
