// 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.
