"As a rule, most scripting language require around 300-350M of virtual memory to load completely".
OOM issues are sometimes hard to discover and annoying. Please raise the default settings to avoid many such issues.

jsub: Raise default memory allocation to 400M

Change 257062 merged by coren:
jsub: Raise default memory allocation to 400M

400M is still reasonable; and 256M was arguably too conservative given it didn't allow most scripting langues.

After discussion on IRC, we'll go with a more generous and round 512M limit.
