No, it won't, or at least the delay will be trivial. Every block has an equal likelihood of containing the key. It does not matter whether the block has been assigned once, twice or fifty times, so long as unchecked blocks exist to be assigned the chance of each block containing the key is exactly 1/(#UncheckedBlocks) no more, no less. The only additional time is the time spent actually assigning the block, a few milliseconds.
On the other hand if someone is requesting blocks and then returning them as checked, without actually checking them, then this will cause major delays. But this is a malicious act.
