I'm not sure what I messed up the first time, but I am able to reproduce
reliably now, with and without lz4. It looks like we have a workaround
in place that significantly increases the number of simultaneous locks
acquired during indexing:
#define XLR_MAX_BLOCK_ID 199
So that's in need of resolution. I'd expect gin and gist to be pretty
flaky until we fix that.
