Hmm this is somewhat odd, I now get a different behaviour, it must have
been a recent CVS checkout of ECL from a few days back (my current one
behaves as follows:)

ECL CVS checkout from today on NetBSD-5, built with:

export CFLAGS="-march=i686 -O2 -g"
export LDFLAGS="-g"
./configure --prefix=/usr/local/ecl --enable-unicode --enable-threads --with-__thread=no --enable-rpath --with-clx

Console interrupt

Available restarts:

1. (CONTINUE) CONTINUE
2. (INTERRUPT-PROCESS) Interrupt a certain process.

While with the ECL release (built with the same flags on the same OS, except -g)
