Hi Hillf,

Do you see the bug? Jakub said he can't repro.
The repro has these suspicious bpf syscalls and there is currently
some nasty bpf bug that plagues us and leads to random assorted
splats.
I've run the repro as "./syz-execprog -repeat=0 -procs=6 repro"  and
in 10 mins I got the following splat, which indeed suggests a bpf bug.
But we of course can have both bpf stack overflow and a memory leak in tls.
