when starting a daemon from the console, the console will not close

Try, e.g:

$ exit
Shell exits, but console window persists until syslogd is terminated.
Workaround:
setsid();
+ #ifdef __CYGWIN__
+ FreeConsole();
+ #endif
According to syscall.cc:setsid(), FreeConsole() should be called if a
tty exists and no files are open.
Yep, so, as CGF noted, try
$ /usr/sbin/syslogd >/dev/null 2>&1 </dev/null
$ exit
However, the main question is whether syslogd *should* close the file
descriptors if it doesn't intend to write to them. I'm not familiar
enough with syslogd's operation -- if it normally writes to stdout/stderr
(or reads from stdin), the above is the only way to get the shell to
close. If syslogd never reads/writes to standard filehandles in daemon
mode, it should close them itself (i.e., this is a syslogd bug).
