Q: Do DNA polymerases hop over gaps?

Salvete, molbio godesses and gods!

Please imagine two primers with a small gap (1 to 4 nucleotides 
long) between them annealed to a piece of DNA. Will polymerases stop 
at this gap  waiting for nucleotides to come and do e.g. some 
proofreading while hanging around ? 
or will they just run over the gap, leaving it unfixed?

Any ideas, opinions, knowledge?

I Appreciate all input.
