# A race can happen on conn->last_errno if replica client is reading/writing
# data in IO thread and main thread is calling connAddrPeerName for some reason
# (f.e genRedisInfoString/roleCommand...).
# Not worth the additional code for synchronization as:
# - errno is thread-safe according to POSIX std
# - we don't support systems that allow word tearing, i.e last_errno value would
#   be a correct value at the end - either the errno from main or from IO thread
# - even if we fix the data race on last_errno we still have the problem of it
#   being set to either errno unless we pause the IO thread during main-thread's
#   execution which would incur too big of a cost.
# - the race happens rarely
