Unsafe calls to those seem highly unlikely.\n\n* Unsafe pthread_detach callers probably want to switch to\n pthread_attr_setdetachstate instead, or using pthread_detach(pthread_self())\n from the new thread\u0027s start routine rather than doing the detach in the\n parent.\n\n* pthread_join calls should be safe anyway, because a joinable thread won\u0027t\n actually exit and unmap until it\u0027s joined. If you\u0027re joining an\n unjoinable thread, the fix is to stop marking it detached. If you\u0027re\n joining an already-joined thread, you need to rethink your design.\n\n* Unsafe pthread_kill calls aren\u0027t portably fixable. (And are obviously\n inherently non-portable as-is.) The best alternative on Android is to\n use pthread_gettid_np at some point that you know the thread to be alive,\n and then call kill/tgkill directly.

This allows something that might be\n a derivative of app_process to be started with an environment variable\n being enabled.\n- get_malloc_leak_info() used to return one element for each pointer that\n had the exact same backtrace.

It turns out ddms already\n automatically coalesces these, so the old method simply hid the fact\n that there where multiple pointers with the same amount of backtrace.\n- Moved all of the malloc debug specific code into the library.\n Nothing related to the malloc debug data structures remains in libc.\n- Removed the calls to the debug malloc cleanup routine. Instead, I\n added an atexit call with the debug malloc cleanup routine. This gets\n around most problems related to the timing of doing the cleanup.\n\nThe new properties and environment variables:\n\nlibc.debug.malloc.options\n Set by option name (such as \"backtrace\").
