It seems that we're getting a tcp disconnect (ECONNRESET) on when doing
that shutdown() on postcopy_qemufile_src. The one from commit 6621883f93
("migration: Fix potential race on postcopy_qemufile_src").

I'm trying to determine why that happens when other times it just
returns 0 as expected.

Could this mean that we're kicking the dest too soon while it is still
receiving valid data?
