[svn-r20048] Description:
Bring Coverity changes back to trunk:
r19733:
Fix memory leak in h5perf_serial. Global buffer "buffer2" was allocated at the
beginning of do_sio() but never freed. Added call to free() at end of do_sio().
r19734:
Fix memory leak in iopipe. Buffer "the_data" was allocated at the beginning of
main() but never freed. Added call to free() at end of main().
Tested on:
Coverity branch in daily tests & Mac
