* MAX_NO_OF_CONNECTIONS must be small enough. Each connection takes one
* file descriptor, and it is important that there are a few descriptors
* left so that it is possible to save the data base. lyskomd might crash
* if this number is too big and that many connectionattempts are made
* simultaneously.
*
* The following descriptors are open by LysKOM:
* stdin, stdout, stderr (stdin and stdout could probably be closed.
* The log() function prints to stderr.)
* TEXTFILE_NAME (always open)
* DATAFILE_NAME (often open)
* STATISTIC_NAME (open after a SIGUSR1)
* Thus, the max number of connections is the number of available file
* descriptors minus six. This has not been fully tested for a long
* while, so we subtract eight just to be on the safe side. That still
* gives 56 simultaneous users on a sun4, and that is enough for the
* time beeing. (If you need more connections you can ran a mux. Send
* mail to kom@lysator.liu.se for more info.)
