3) becuase -> because
4) fallthru -> fall through
5) uncoming -> upcoming
6) ans -> and
7) requrested -> requested
8) peforming -> performing
9) heartbearts -> heartbeats
10) parametrizing -> parameterizing
11) uninit -> uninitialized
12) bufgr  -> bufmgr
13) directi -> direct
14) thead -> thread
15) somthing -> something
