Andy Isaacson commented on HDFS-3634:
-------------------------------------

{code}
+void sleepNoSig(int sec)
+{
+  struct timespec req, rem;
+
+  req.tv_sec = sec;
+  req.tv_nsec = 0;
+  memset(&rem, 0, sizeof(rem));
+  nanosleep(&req, &rem);
+}
{code}
Is this supposed to resume the sleep if interrupted?  If so we need a loop. If 
not, we can drop {{rem}} and just {{nanosleep(&req, 0);}}.

> We should have a self-contained, mavenized FUSE unit test which runs as part 
> of the normal build and can detect problems.  Of course, because FUSE is an 
> optional build component, the unit test won't run unless the user has FUSE 
> installed.  However, it would be very useful in improving the quality of 
> fuse_dfs and detecting regressions.
