See also this libsubprocess unit test
It runs cat as a subprocess and tries to ship data to and from it.
bool iostress_run_check (flux_t *h,
const char *name,
bool direct,
int stdin_bufsize,
int stdout_bufsize,
int batchcount,
int batchlines,
size_t linesize)In that invocation,
iostress_run_check (h, "tinystdout", false, 0, 128, 1, 1, 256)stdin_bufsize is the default size but stdout_bufsize is 128 bytes. Then we send a 256 character line. The result is deadlock.
