*	Fix potential TLS-related memory corruption.	Jason Evans	2013-01-31	1	-0/+43
\| \| \| \| \| \| \| \| \| \|	Avoid writing to uninitialized TLS as a side effect of deallocation. Initializing TLS during deallocation is unsafe because it is possible that a thread never did any allocation, and that TLS has already been deallocated by the threads library, resulting in write-after-free corruption. These fixes affect prof_tdata and quarantine; all other uses of TLS are already safe, whether intentionally (as for tcache) or unintentionally (as for arenas).
*	Implement Valgrind support, redzones, and quarantine.	Jason Evans	2012-04-11	1	-0/+24
	Implement Valgrind support, as well as the redzone and quarantine features, which help Valgrind detect memory errors. Redzones are only implemented for small objects because the changes necessary to support redzones around large and huge objects are complicated by in-place reallocation, to the point that it isn't clear that the maintenance burden is worth the incremental improvement to Valgrind support. Merge arena_salloc() and arena_salloc_demote(). Refactor i[v]salloc() to expose the 'demote' option.
