[slime-devel] repl-thread

[Luke Gorrie]

Ahoy,

I checked in a change so that the REPL has a dedicated thread for
evaluating all expressions. Hopefully by reusing the same thread we're
less vulnerable to the implementation-specific threading nuances,
e.g. now *, +, **, etc are working again in SBCL.

It seems to work fine under SBCL and LispWorks. If someone running
Franz or OpenMCL could confirm that I didn't break them I'd be much
obliged.

P.S., I'm finding the multithreading code quite comprehensible with
this simple message-passing interface. Nice one Helmut!
