 This error has been causing failure in sql-de-lite, fps, and hashes tests
 on salmonella since 2012/01/06.  It succeeded on salmonella 2012/01/04.
 Both runs are reported to be in Chicken 4.7.4 series but it is not known
 yet exactly which sha1 hash.

 17:18:21 < sjamaan> What exactly is it doing?
 17:22:10 < zbigniew> hash-table-ref of a string=? hash table, probably via
 lru-cache
 17:22:17 < zbigniew> failure beings here: http://tests.call-
 cc.org/master/linux/x86/2012/01/06/salmonella-report/tests/sql-de-
 lite.html
 17:22:28 < zbigniew> begins
 17:22:33 < zbigniew> ok here: http://tests.call-
 cc.org/master/linux/x86/2012/01/04/salmonella-report/tests/sql-de-
 lite.html
 17:23:49 < sjamaan> Can't reproduce with a simple hash-table test
 17:27:24 < zbigniew> other eggs are apparently having the same issue

 /salmonella-report/test/hashes.html (at end of tests)
 17:28:28 < sjamaan> So this has been broken for months. Why didn't anyone
 report this?
 17:29:07 < zbigniew> probably no one affected is using master
 17:29:18 < zbigniew> nomads, but it's because it depends on sql-de-lite,
 so that doesn't count
 17:31:40 < zbigniew> all right, ultimately, it looks like only fps and
 sql-de-lite are having a problem; hashes counts but has a bunch of other
 problems
 17:32:10 < zbigniew> i assume sql-de-lite's problem is due to lru-cache
