i think it can be done, if you want to.
one solution would be to put the accept/1 in another process and use 
cast/2 to send the socket to the gen_server.
if you want the accept/1 in the gen_server processs the problem is that 
accept/1 might block which would cause the gen_server to timeout. but 
use accept/2 and have the timeout shorter than the timeout for the 
gen_server.
