[Qemu-devel] [PATCH 3/5] linux-user: remove signal handler before calling abort() |
Date: |

From: Riku Voipio <address@hidden>
Qemu may hang in host_signal_handler after qemu has done a
seppuku with cpu_abort(). But at this stage we are not really
interested in target process coredump anymore, so unregister
host_signal_handler to die grafefully.
