Locking the scheduler is not enough, as lwIP's tcpip_thread might be in the 
middle of something when you just lock the scheduler.

Even lwIP 1.1.1 has the tcpip_callback() function. You just have to create a 
callback function to be called which then calls dhcp_start(). See other usages 
of tcpip_callback() throughout the stack for an example.
