If you have 

(applied)
patchA
patchB
patchC
patchD
patchE
patchF
patchI
patchJ
patchK
patchL
----
(not applied)
patchX
patchY

then its very suboptimal to have to do 

qpop patchA
qpush -move patchC
qpush -move patchD
qpush -move patchE
qpush -move patchF
qpush -move patchI
qpush -move patchJ
qpush -move patchK

just to do an effective qpop -move patchB 

I often have patch depths of 30 or more...

This should be done in code by Mercurial
