This shouldn't be necessary. The NETCONNECTION structure should have 
been re-initialized to its post-NETCON_init state after calling 
NETCON_close. There are two possible reasons I can think of that would 
cause a crash. The first is the NETCONNECTION stuff not being 
thread-safe. The second is possible ref-counting issues on the SSL 
method object "meth". Can you show me the backtrace?
