When I save Mathematica notebook files, I get a file with the notebook
content plus about 6MB of Null-Bytes at the end of the file. After
deleting the Null bytes in the file, everything works fine again.

Does anybody know about this problem and possible solutions? 
Is it due to the Linux emulation on FreeBSD? 

I am using
	FreeBSD 2.2.1-RELEASE
	XFree86 v3.2
	fvwm2
	Pentium 150MHz
	Mathematica 3.0 in a.out format

When running Mathematica, I get only several lines of the well know and
harmless(?) message:

	LINUX: 'ioctl' fd=8, typ=0x89(), num=0x27 not implemented
