The "tcl session" object holds an interpretor (Tcl_Interp) and the "snmp
session" performs its requests via "tcl session" eval operations. I made this
thread-safe by wrapping a token (recursive mutex) around all Tcl calls in the
tcl session object. This is by no means optimal but has been doing the job.
