+    <braunr> hm, gdb isn't able to determine which thread is running when
+      attaching to a process

+    <braunr> woah, now that's a weird message !
+    <braunr> when using gdb on a hanged ext2fs :
+    <braunr> Pid 938 has an additional task suspend count of 1; clear it? (y or
+      n) 
+    <braunr> when hanged, gdb thinks the target task is already being debugged
+      :/
+    <braunr> no wonder why it's completely stuck
+    <braunr> hm, the task_suspend might actually be the crash-dump-core server
+      attempting to create the core :/
+    <braunr> hm interesting, looks like a problem with the
+      diskfs_catch_exception macro
+    <pinotree> braunr: what's up with it?
+    <braunr> pinotree: it uses setjmp
+    <braunr> hm random corruptions :/
+    <braunr> definitely looks like a concurrency problem
