+- Test whether file with DRD client requests is installed properly.
 - Let DRD print a warning message when, after 30s runtime, the ratio of
   the number of mutex lock / unlock calls to the number of executed basic
   blocks exceeds a certain threshold. Test with Firefox and nautilus.
 - Continue discussion about unification of DRD and Helgrind client requests.
-- Propose renaming exp-drd back to drd.
+- Propose to rename exp-drd back to drd.
 - Memory pool support.
 - Add locking order checking. Start from the following information:

 Limitations
 ~~~~~~~~~~~
-- Does not work with a glibc library compiled with linuxthreads -- NPTL is
-  required for proper operation.
 - openSUSE 10.3, ppc: unless the glibc debuginfo packages is installed,
   false positives are reported on ld.so.
   See also https://bugzilla.novell.com/show_bug.cgi?id=396197.
+- ppc: reports false positives on atomic operations (VEX limitation). See also
+  https://bugs.kde.org/show_bug.cgi?id=162354.
+- Does not work with a glibc library compiled with linuxthreads -- NPTL is
+  required for proper operation.
+- Does not work when compiled with gcc 2.95 -- probably a bug in the
+  optimizer of gcc 2.95.
