--- Comment #6 from zephyrus00jp <ishik...@yk.rim.or.jp> --- I needed to implement the support for these two system calls because somehow I found that running thunderbird under valgrind for mozilla test suite called mochitest forced valgrind to create so many tasks (> 1500) and it blew up. (--max-threads=1500 did not help.) I filed a bug at mozilla bugzilla. See https://bugzilla.mozilla.org/show_bug.cgi?id=1629433 Running thunderbird binary under valgrind while trying to run mochitest requires way TOO MANY threads (> 1500) !? Now that the supporting these system calls via this patch does not seem to change the blowup behavior. Now I have a feeling that there are so many tasks created related to futex_wait_cancellable (related to syscall 202), I feel there is a bug in the handling futex calls under x86_64 linux, but then I am not sure why we don't hear from Firefox people about the similar problem... Anyway merging of the tidied up patch to the source repository of valgrind will be appreciated. If also, someone can take a look at the log posted at mozilla bugzilla See https://bugzilla.mozilla.org/show_bug.cgi?id=1629433 and shed some light on the issue, I would appreciate it very much.
