One would have to evaluate the costs associated with this.  On one hand,
this would slow down external packages.  On the other hand, this may
allow us to the `initial-exec' TLS access model (as noted by Andy on
IRC), which can be a significant performance improvement.  What I
dislike is that it would make external packages second-class citizens,
compared to code part of guile-core.

Anyway, that's too late for 1.8 I suppose.
