Journals, Magazines & the drag of exclusive submissions

It can be a frustrating process for writers and scholars, the process to publishing an article in a journal or magazine. Following the arduous task of actually producing a work of publishable quality -- what did Hemingway say? ... sit down at the writing desk and open a vein -- then comes the job of pitching and querying and waiting for acceptance and rejection.

And, with that is the dreaded request for "exclusive submissions."

While many -- in fact, the majority that I pay attention -- journals and magazines accept simultaneous submissions with the simple request to "please notify us if the piece is accepted elsewhere," some publications put an unrealistic requirement on writers to give exclusive reading rights for several months with no promise of publication. 

While I understand reservations about simultaneous submissions out of concern for the time of submission readers and editors, it's equally challenging for writers and scholars to concede to exclusive submissions and wait for months at a time only to receive a single rejection and start again. Granted, writers certainly have the freedom to simply not submit to publications with that requirement, I personally feel like it's a flaw in the system.
