function logstat (testscript, threads, jit_controls, factory_controls, pji_controls)
%LOGSTAT run a GraphBLAS test and log the results to log.txt
%
% logstat (testscript, threads, jit_controls, factory_controls, pji_controls)
%
% threads: defaults to threads{1} = [4 1], which uses 4 threads and a tiny
% chunk size of 1.
%
% jit_controls: a parameter for GB_mex_jit_control (0 to 5: off, pause, run,
% load, on). JIT kernels from the prior test are always cleared from the JIT
% hash table, and then the JIT is renabled. This is to prevent a sequence of
% many tests to run out of memory from loading too many JIT kernels. If
% jit_controls is empty, the JIT control is left unchanged.
%
% factory_controls: 1 to enable the factory kernels, 0 to disable them.
% If empty, default is enabled.
%
% pji_controls: a list of integers in the range 0 to 7, where each integer
% is a 3-bit number with [pji]_control. Defaults to [0]
