This also works with the 2.4.24 Linux kernel (Slackware 9.1):

chris@roamer:~$ more testfile.txt
Let's try this in Linux
chris@roamer:~$ ls -al testfile.txt
- -rw-r--r--    1 chris    users          24 Apr  7 12:43 testfile.txt
chris@roamer:~$ testfile.txt>testfile.txt
- -bash: ./testfile.txt: Permission denied
chris@roamer:~$ more testfile.txt
chris@roamer:~$ ls -al testfile.txt
- -rw-r--r--    1 chris    users           0 Apr  7 12:44 testfile.txt
chris@roamer:~$

Tried with +x too:

chris@roamer:~$ mv testfile.txt testfile
chris@roamer:~$ echo "ls -al">testfile
chris@roamer:~$ ls -al testfile
- -rw-r--r--    1 chris    users           7 Apr  7 12:48 testfile
chris@roamer:~$ chmod u+x testfile
chris@roamer:~$ ls -al testfile
- -rwxr--r--    1 chris    users           7 Apr  7 12:48 testfile*
chris@roamer:~$ ./testfile
total 346520
<My ls snipped>
chris@roamer:~$ testfile>testfile
- -bash: ./testfile: Text file busy
chris@roamer:~$ ls -al testfile
- -rwxr--r--    1 chris    users           0 Apr  7 12:49 testfile*
