why not:

processa ($cat filelist.txt)
processb

Where processa receives the lines from filelist.txt as char** agrv list
in int main(int argc, char** argv). After all threads in processa
complete processa returns and processb is executed than.

not quite. It receives the whitespace-separated tokens from filelist.txt
as the argv list. His version has processa executed once per line, and
it receives the whitespace-separated tokens from the given line on each
run, which is better, but still not perfect.
