! // This test intentionally disables caching of Elf sections during symbol lookup
! // with WhiteBox.disableElfSectionCache(). On platforms which do not use file
! // descriptors instead of plain function pointers this slows down the lookup just a
! // little bit, because all the symbols from an Elf file are still read consecutively
! // after one 'fseek()' call. But on platforms with file descriptors like ppc64
! // big-endian, we get two 'fseek()' calls for each symbol read from the Elf file
! // because reading the file descriptor table is nested inside the loop which reads
! // the symbols. This really trashes the I/O system and considerable slows down the
! // test, so we need an extra long timeout setting.
