 Hum, after some more testing (well, unexpected crashes actually) it
 seems like the cat(1) trick is not necessarily the true workaround.
 Sometimes, even this trick fails to have subsequent read accesses
 working.
 
 But maybe it's just a matter of un-mounting and re-mouting the
 filesystem... Indeed, I need to perform some more tests but I've been
 doing this with 100% succes so far:
 
 1. mount
 2. cat file.txt
 3. un-mount
 4. re-mount
 5. do whatever I want, even subversion operations
 
 Actually, I still pray each time I do a simple svn update. But
 statistically, this gives me the best results.
 
 Dmitry, could you try this method to confirm?
 
 BTW, I've just upgraded to 5.3-RELEASE last night so we'll see in a
 short while if the problem is still relevant with this version.
