For the simplest kinds of scripts that contain little other than a
tracing print* (so there are no global variable locks, and maybe
very little context space in play), we could allow the script to
be run in a reentrant fashion.

This could mean having a small number of context slots on a 
per-cpu basis.

If there are multiple print* statements in the handler, and if
we wish to support atomicity for the group, the context could
be enlarged to contain an intermediate print buffer, and amend
the runtime as necessary.

See also bug #9967.
