Not really; that was fixed in 2009. Read on in the thread: 
http://cygwin.com/ml/cygwin/2009-05/msg00120.html

Nevertheless, I've seen strange problems myself on Windows. Twice, when 
I started digging into some hangs, I found the hanging command to be a 
find:
+ /usr/bin/find 
/cygdrive/c/localdata/hg/build-infra-jdk8/build/windows-x86-normal-server-release/images/c 
-type f -a '!' -name '_the.*' '(' -name FALSE_DUMMY -o -name '*.java' -o 
-name '*.c' -o -name '*.h' ')'

Process explorer stated that this process was "suspended", which is a 
bit weird. In Windows that's a debug state which a process should not 
normally reach. Resuming it didn't have any effect though (not 
surprising). My guess is that it's some kind of half-disabled assert in 
the cygwin code.
