Multiple halidetuner instances cannot run concurrently

[jrk]

Even running a separate --make-settings-file process will conflict with and kill any running tuning process. Without investigation, I presume this is because of hard-coded non-unique tmpfile paths.

@jansel is this just because everybody tries to use /tmp/halide.bin?

yes, the problem is /tmp/halide.bin -- this is leftover from a older bug where we leaked processes (now fixed) and needed an easy way to killall.

if your running multiple copies you may want to point at separate --database=, or use something like postgres which handles more than one connection well.
