That shouldn't be a problem. Note that almost every DHCP transaction 
doesn't block, a packet arrives and a reply is sent without waiting. The 
only exception to this the ping-check, which waits three seconds, during 
which other DHCP transactions must wait. HOWEVER, if a situation arises 
where DHCP requests are being delayed, then dnsmasq temporarily abandons 
doing the ping checks, so under no circumstances will DHCP transaction 
be delayed long enough for a client to time-out.


Cheers,

Simon.
