9109861 amd64 hangs at startup
10110301 ditto
11111554 valgrind crashes with Cannot allocate memory
12111809 Memcheck tool doesn't start java
13111901 cross-platform run of cachegrind fails on opteron
14113468 (vgPlain_mprotect_range): Assertion 'r != -1' failed.
15 92071 Reading debugging info uses too much memory
16109744 memcheck loses track of mmap from direct ld-linux.so.2
17110183 tail of page with _end
18 82301 FV memory layout too rigid
19 98278 Infinite recursion possible when allocating memory
20108994 Valgrind runs out of memory due to 133x overhead
21115643 valgrind cannot allocate memory
22
23Will fix in 3.1. Long delay seems to be caused by amd64-Gentoo kernel
24not liking large mmap/munmap requests. Other bugs also look like
25aspacem problems.
