`MDBX_TXN_OVERLAPPING` Error coming from 2.60beta sync against xlayer #1451

It seems like there must be some related to our db read/write in the early syncing stage. We've encountered this error a few times.

[EROR] [11-12|12:05:47.579] Staged Sync                              err="mdbx_txn_begin: MDBX_TXN_OVERLAPPING: Overlapping read and write transactions for the current thread, label: chaindata, trace: [kv_mdbx.go:767 kv_mdbx.go:907 stageloop.go:215 stageloop.go:110 stageloop.go:73 asm_amd64.s:1650]"

The odd thing is it's not universally reproducible. In one system we were able to sync paste this stage successfully. In another system the error over and over again after doing a clean sync.
