cast -O and -R are dreadfully slow (Support #416)

I'm not certain whether this is a bug or expected behavior, but it is a bit disturbing. All I am trying to do is have Sorcery recast spells that optionally depend on mono so I can fold them against mono. In the time this command has run, I could have brute-force rebuilt nearly 2/3 of the installed spells.

If I am understanding the command structure and executing it correctly, we have either an algorithm issue or (unlikely) an inherent limitation in shell-scripting. In any case, it shouldn't be happening. I'm not familiar/comfortable enough with Sorcery internals (yet), but am more than willing to help diagnose and provide any further information. I'll attempt to duplicate this week on the KVM farm and, until I can duplicate on other systems, I will list as "support" rather than "bug".

Command is: cast -O ask-yes -R mono Sorcery gurus - is this even the right command? If not, let's close this as PEBKAC (problem exists between keyboard and chair), and I'll see what I can do about updating the context help and man pages.

Processes:

16870 pts/2 SN+ 0:49 bash /tmp/sorcery/cast/16870/casting.safe -O ask-yes -R mono
28980 pts/2 SN+ 40:32 bash /tmp/sorcery/cast/16870/casting.safe -O ask-yes -R mono

Other activity on system: None except for glances
System load/resources: Not an issue (i7 + 32GB)
