If the .eh_frame section does not get paged into memory, then I think 10% is
acceptable (remember that the in-memory penalty is essentially zero). For
kernels or embedded code where there is no paging, the acceptable figure
is smaller, and I suspect that folks would use -fno-exceptions no matter
how small the penalty is (unless it is 2% or less).
