  Backout changes trying to inherit floating-point environment, although
  POSIX (susv3) requires this, but it is unclear what should be inherited,
  duplicating whole 387 stack for new thread seems to be unnecessary and
  dangerous. Revert to previous code, force a new thread to be started with
  clean FP state.
