30s in java.io.File.listFiles() in other than AWT thread seems to slow down a single query to File.canRead in AWT thread. Either the system is too slow or overloaded. I really don't know what to do with this. Closing as won't fix.

please look through the latest reports, they seem to have been matched incorrectly, several are for bug 218234 for sure

Slow file system is not justification of IO activity in EDT.
49 reports => P2
