After this change firefox 4.0b8pre built from mozilla trunk crashes with
SIGBUS while starting, on /head@r214363M amd64. It may be related to

  $ js
  Assertion failure: stackBase, at jsnativestack.cpp:217

and the calls preceding it

  pthread_attr_get_np(thread, &sattr);
  pthread_attr_getstack(&sattr, &stackBase, &stackSize);

java/openjdk6 doesn't start, too

  $ java
  #
  # A fatal error has been detected by the Java Runtime Environment:
  #
  #  Internal Error (os_bsd_x86.cpp:876), pid=10495, tid=34389128704
  #  Error: pthread_attr_get_np failed with err = 34
