0_lib/functions.sh is executed twice

[843723683]

Hi，
0_lib/functions.sh is executed twice：

1. In "runtest.sh"->Line 27 “[ -f $LIB_FUNCTIONS ] && source $LIB_FUNCTIONS”
2. In "runtest.sh"->Line 50 or 53 "t_Process <(/usr/bin/find ./tests/0_*/ -type f|sort -t'/' )"

I think it only needs to be executed once.Proposed two modifications

1. "runtest.sh"->Line 50 or 53 change！ “t_Process <(/usr/bin/find ./tests/0_c*/ -type f|sort -t'/' )”

2. chmod a-x 0_lib/functions.sh

Thank you
