Gasp terribly, seeing holes (4)

I believe the answer is:

gaps

'holes' is the definition.
(I've seen this in another clue)

'gasp terribly' is the wordplay.
'terribly' indicates an anagram.
'gasp' is an anagram of 'GAPS'.

'seeing' is the link.

(Other definitions for gaps that I've seen before include "Breaks, spaces" , "Breaks or openings as in hedge or fence" .)

I've seen this clue in The Mirror.
