If you increase the delay, you will skip over a number of items in the
buffer, but otherwise, no, you won't lose any data, so this isn't what
you want to use to throw away data.

Calling a function externally probably isn't what you want to do if
you have a specific set of items you want to toss. If you're just
throwing away any set of items, then this should work. If you have
specific items (or items at a specific time or time delta), then
you'll want to do something with stream tags to tell the block to toss
items at a particular sample.
