%% Reproducer attempt for https://github.com/erlang/otp/issues/7801
%% It's supposed to model the couch_file.erl from Apache CouchDB
%%
%% Example run:
%%   c(ioblock), ioblock:go("./junk.bin", 8192, 60, 4000).
%%   - Create a temporary junk.bin file with 8GB of random data
%%   - Spawn 60 gen_servers to handle preads from the file
%%   - Spawn 4000 caller processes to call the servers with pread commands
%%
%% Note: run the first time without measuring to create the larger file.
