[Openmcl-devel] Bug when writing to broken pipe?

Thanks a lot Gary.
? (#_signal #$SIGPIPE #$SIG_DFL) is a fix for my problem.
I wrote a small reporting tool which the user might pipe to Unix less. It may be, output takes some time and the user reasonably decides to press letter q to abort the analysis. In this case the non-Lisp-aware user would be confronted with the Lisp debugger. I'm glad, I can avoid this situation now.
Thank you.
Regards
Andreas
