Comment (by nickm):

 control_event_hs_descriptor_receive_end worries me a bit.  It takes a fmt
 argument as a char*, and bypasses the GCC printf argument checking.
 Instead, why not give it an extra const char * argument to receive either
 "FAILED" or "RECEIVED"?

 In test_hs.c, I'd suggest adding TT_FORK to the flags field, so that the
 tests are run in a subprocess.
