As a micro-optimization one might want to replace the line above with

  +      if (UnsafeLispSocket || cfg->LispServerPort != LispServerPort || strcmp(cfg->LispServerIP, LispServerIP))

Comparing two longs should generally be faster than calling strcmp and
it's not unlikely that that the different Lisp images will be on the
same machine but use different ports.

Cheers,
Edi.
