| 10 | This controls whether arguments in guest processes should be shown on |
| 11 | the host's ps output. |
| 12 | Enabling this option hinders debugging on some recent GDB versions |
| 13 | (because GDB gets "confused" when we do an execvp()). So probably you |
| 14 | should disable it. |

| 20 | This option enables a debugging interface which allows gdb to debug |
| 21 | the kernel without needing to actually attach to kernel threads. |

| 54 | Track the maximum kernel stack usage - this will look at each |
| 55 | kernel stack at process exit and log it if it's the deepest |
| 56 | stack seen so far. |
| 57 | |
| 58 | This option will slow down process creation and destruction somewhat. |
