BLODA problem while configuring

[Ken Brown]

I've recently started getting write errors ("Device or resource busy") 
at random times while building texlive, which I've successfully built 
many times in the past.  It happens during configuration when there is 
an attempt to write a file (config.status, contest.c,...).  But only a 
few such write attempts fail, and I haven't noticed a pattern.

One strange thing is that I've seen this error only while building 
texlive.  (For example, I can still build emacs without a problem.)  I 
don't know what might be happening in the texlive build that would 
trigger this.

I suspect BLODA because of the random nature of the errors and also 
because the problem occurs on one of my computers but not a second.  I 
noticed that Chuck reported the same error in his announcement of 
autoconf2.5-2.64-10

   http://sourceware.org/ml/cygwin/2009-08/msg00640.html

but this was during parallel test execution, so it may be unrelated.  I 
tried reverting to autoconf2.5-2.63-10 and still got the error.

The only recent change I can think of that might be BLODA related is 
that AVG anti-virus was updated to version 9.0.  But that also happened 
on my other computer that doesn't exhibit the problem.  And AVG is not 
on the BLODA list.

I would appreciate any suggestions as to how I can track this down. 
Cygcheck output is attached.  (I'm using Thunderbird and followed Dave's 
advice about configuring it, so I hope the attachment really shows up as 
an attachment in the archives this time.)
