MFC r284593: MFV r284412: 5911 ZFS "hangs" while deleting file
illumos/illumos-gate@46e1baa6cf6d5432f5fd231bb588df8f9570c858
https://www.illumos.org/issues/5911
Sometimes ZFS appears to hang while deleting a file. It is actually
making slow progress at the file deletion, but other operations
(administrative and writes via the data path) "hang" until the file
removal completes, which can take a long time if the file has many
blocks. The deletion (or most of it) happens in a single txg, and the
sync thread spends most of its time reading indirect blocks...
