+/* The file has been patched following the advice of Uwe Ohse
+/* <uwe@ohse.de>:
+/* --------------------------------------------------------------
+/* this patch fixes a problem with sdbms .dir file, which arrises when
+/* a second .dir block is needed for the first time. read() returns 0
+/* in that case, and the library forgot to initialize that new block.
+/*
+/* A related problem is that the calculation of db->maxbno is wrong.
+/* It just appends 4096*BYTESIZ bits, which is not enough except for
+/* small databases (.dir basically doubles everytime it's too small).
+/* --------------------------------------------------------------
+/* According to Uwe Ohse, the patch has also been submitted to the
+/* author of SDBM. (The 4096*BYTESIZ bits comment may apply with a
+/* different size for Postfix/TLS, as the patch was sent against the
+/* original SDBM distributiona and for Postfix/TLS I have changed the
+/* default sizes.
