Is invoking exit(2) in a library the right thing to do?

[Andreas Metzler]

Hej,

currently log_fatal() ends up invoking exit(2). Is this really the
right thing to do? It does not give applications using libgcrypt any
chance to sanely handle fatal errors afaiui, for example by falling
back on non-tls mode.
