[talk] Permission is denied when I try to run certain programs

[Thomas Levine]

My OpenBSD 6.1 system is in a state where I cannot run certain programs
because of a lack of permission. What could the issue be? Perhaps
related, this started happening around the same time when I started
getting kernel panic upon trying to create a softraid device for my
encrypted partition, which has always worked before. Both of these
issues started right after somebody unplugged my computer's while it was
running, but people have done that many times without these issues. It
is possible that I broke something while trying to fix something else.

This happens with python3.6, for example. Most programs seem fine
though.
