[slime-devel] Problems starting SLIME

[Stelian Ionescu]

If I save an image containg latest SWANK and try to start SLIME with it,
I get an error. OTOH, if I start SLIME with an image that doesn't
contain SWANK(loading it on the spot), all works well.
I've traced back the origin of this problem to the commit of Sun Aug 3
18:23:10 entitled "Add some flow-control."
