Hi Thomas,

I was just troubleshooting what looks like a very similar issue.  I believe
this is fixed in a later version of stunnel, which you can get from
stunnel.org and compile yourself from source.

This is the ChangeLog entry that I think addresses your problem:

  - Signal pipe set to non-blocking mode.  This bug caused hangs of stunnel
    features based on signals, e.g. local mode, FORK threading, or
    configuration file reload on Unix.  Win32 platform was not affected.

I have just updated from the official Oneiric version to this one, so I
don't yet know if it will fix the problem long-term, but I think my odds
are not too bad.

Hope this helps,
