Growing the text table may do nothing but increase the time your
machine can be up until it dies.  I understand that under some
circumstances, when an NFS server fails (times out) when the client is
trying to demand-load text segment pages from the image file, the
client's kernel may lose a text table slot.  And if you run out of text
table slots this way?  The only cure I know of is to reboot the client.

The simple way is to patch ntext in /vmunix and reboot:

	# adb -w /vmunix
	_ntext?D
	_ntext:
	_ntext:		28
(Hmmm, 28 slots?  Let's up it to 50.)
	_ntext?W 0t50
	_ntext:		0x1c		=	0x32
	$q
(There.  Now reboot....)
	# /etc/fastboot

(Some things can be patched in the running kernel and take effect
immediately.  _ntext is not one of these; you must patch the kernel
file and reboot.)

This change will go away next time you build a kernel.  Most kernel
configuration schemes have a way to override the default values for
things like ntext; see param.c in your system configuration directory.
