@bjarthur mentioned that `QRSHManager` can increase reliability on some systems:

> Julia workers can frequently timeout waiting for the standard output files to appear. In this case, it’s better to use the QRSHManager, which uses SGE’s qrsh command to bypass the filesystem and captures STDOUT directly.

What errors should I expect to see if this is my situation?
