It too might be somewhat inclined to move stuff around more than glibc if reallocing alot, but don&apos;t quote me on that.&lt;/p&gt;</comment>
                            <comment id="10705" author="mike" created="Fri, 11 Sep 2009 13:51:46 +0000"  >&lt;p&gt;eliot comments that this is probably going to be a bad solution for us in general since realloc calls in tcmalloc generally fail to return the same buffer more often than realloc calls in glibc malloc. we do a lot of reallocs, so that is important.&lt;/p&gt;</comment>
