I'm glad to hear it.  You can install bash from pkgsrc; precompiled
binaries are available.  I always do that myself (but usually build).
less is in /usr/bin.

Is this a bug in NetBSD?  From the man page, it isn't super clear.
For contexts made with makecontext(3), there is apparently no
guarantee that the context won't be munged.

Thanks for tracking this down.
