This situation is already addressed to some extent with our cross-compilation
capabilities.  (See the relevant war story wiki page for an example.)

Unless I am mistaken, sharing buffers by nature increases contention.
Concurrently executing probes would have to use some mutual exclusion
to write into the same buffer.  Plus they would probably have to include
some additional information with every record to identify the script
that produced it.

Perhaps we can lump it in with the flight recorder functionality.
