syslog generally keeps its destination files open:

Code:
[root@localhost log]# fuser maillog
maillog:              4648
[root@localhost log]# ps -efa | grep 4648
root      4648     1  0  2012 ?        00:00:01 syslogd -m 0
root     11294  9649  0 16:20 pts/0    00:00:00 grep 4648
[root@localhost log]#

Obviously two programs can't/shouldn't be writing to the same file. There are also syslog-specific reasons for not wanting to do it this way: What if I'm doing a remote syslog? If you're logging directly to files you don't get to take advantage of that and if you want to build that funtionality in yourself then your job is just that much harder. What if the sysadmin wants your logs to go to two different files? etc, etc.

These are the problems the syslog daemon was created to resolve: make a single program broker access to the logging system, then you can solve common problems in one place and in a way that doesn't lead to programs clobbering the work of others.

Most languages have syslog bindings anyways so there's very little reason to want to do it a different way.
