Hello world,

In looking for a bug in CMUCL I found strange behavior in the
interactions between signals and the fpu control word.

In the demonstration (typescript) you can see that on 2.0.26 the control
word is reset in the signal handler. Shouldn't we document, or change the
behavior?

Groetjes, Peter
