Hi Anton
I'm clueless about #1 because I don't see any mod_rivet function
#2 backtrace seems to hint to a problem with Itcl. There is problem
reconstructing the internal name of a method (ItclMapMethodNameProc) and
this in turn is triggered by a Tcl_DeleteCommandFromToken. Is this
backtrace matched in the log file by the message about the shared Tcl
object? If my hypothesis is correct I gather there is some package
creating Itcl commands whose deletion is triggered when the interpreter
is deleted by mod_rivet (Rivet_ProcessorCleanup) but the process fails
for an internal error.
