Hi, when trying to write a driver that provides a ppdev-compatible API but forwards the data written to the parport to a userspace program, I noticed that Qemu (0.8.2-4etch1 from Debian Etch, but the changelog of 0.9.0 doesn't look like it has been fixed there) doesn't handle interrupted system calls properly, at least as far as the parport emulation is concerned. When the involved ioctl()s get interrupted by a SIGALRM, they don't get restarted, so some port writes get lost.
