You don't need write simple short living workers as gen_server's.

If you need OTP support for them look at _plain_fsm_ module at
Jungerl(http://jungerl.sourceforge.net/). You can convert simple
spawn+loop FSMs with it easily to obey OTP system protocols.

It seems that _proc_reg_ module could be useful too for your
application.
