-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Ugh. There's no clean way to do this that I can find, especially given BOINC's custom handling of stdout and stderr. The closest solution I've found that actually starts to be (thread, context, etc) safe is her e:
https://stackoverflow.com/questions/5419356/redirect-stdout-stderr-to-a- string (The response from Sir Digby Chicken Caesar) And it feels like complete overkill for what's going on. Other hacky solutions exist --freopen() et.al.-- but I don't know if it'll step on the toes of other parts of the boinc-client. I can just do a poor man's timer with a decrement counter, only retrying failing DISPLAYs every $number of minutes, which would ease up on the amount of entries at least. I'm going to keep mulling this over in case I can find out a better way to handle this.
