Warner Losh 77740e7e34 Don't trust TMPDIR if we're setuid root. This is used only for the
backing file for an anonymous (memory based) btree, and I don't think
that any setuid programs actually use it, but it is better to be safe
than sorry.  This has been in my tree for a long time, maybe a year or
more...

Inspired by: Similar changes in OpenBSD, if memory serves (like nearly
a year ago)

============================================
Distribution contents:

Makefile.inc	Ignore this, it's the 4.4BSD subsystem Makefile.
PORT		The per OS/architecture directories to use to build
		libdb.a, if you're not running 4.4BSD.  See the file
		PORT/README for more information.
README		This file.
btree		The B+tree routines.
changelog	List of changes, per version.
db		The dbopen(3) interface routine.
docs		Various USENIX papers, and the formatted manual pages.
hash		The extended linear hashing routines.
man		The unformatted manual pages.
mpool		The memory pool routines.
recno		The fixed/variable length record routines.
test		Test package.

============================================
Debugging:

If you're running a memory checker (e.g. Purify) on DB, make sure that
you recompile it with "-DPURIFY" in the CFLAGS, first.  By default,
allocated pages are not initialized by the DB code, and they will show
up as reads of uninitialized memory in the buffer write routines.
