Hmm..  Well, the first thing I noticed from your report is that the idle 
monitoring thread is waking up too often -- it is never supposed to check 
more frequent then every 10 seconds, but looks like the code has the test 
inverted and it checks at least every 10 seconds.  That is easy to fix, but 
it doesn't explain the problem.

I've duplicated the problem on my system, but at the moment I'm stumped.  I'm 
using pthread_cond_timedwait in order to do a timed wait for a condition (the 
condition is signaled by the main thread to indicate the filesystem is 
shutting down).  It appears that pthread_cond_timedwait never returns when 
running in daemon (background) mode.  But sometimes it appears that 
pthread_create fails to create the idle monitoring thread (but doesn't return 
an error code).

There must be a simple explanation that I'm not seeing yet, because I can't 
believe that the pthread library could be that broken - it would have been 
noticed in other programs long before now.  Thanks for the report, I'll reply 
when I figure something out.
