Typo: "nomally" should be "normally"?

Isn't it better to add a space character just after "request"?

If several cycles happen in the do-while loop, m_wal_write_time should be
updated with the sum of "duration" in those cycles instead of "duration"
in the last cycle? If yes, "+=" should be used instead of "=" when updating
m_wal_write_time?

+                       WalStats.m_wal_sync_time = 
INSTR_TIME_GET_MICROSEC(duration);

Also "=" should be "+=" in the above?
