| 4 | The main event loop is awkward on systems for which procfs isn't |
| 5 | pollable. I think a pollable procfs is a Solaris invention so most SVR4 |
| 6 | systems have this weakness. On Solaris, strace runs as a single |
| 7 | controlling process. This is a big improvement if you are debugging a |
| 8 | lot of processes at once. |

| 10 | There is no thread support but it wouldn't be very difficult to add it. |
