K 10 svn:author V 3 bde K 8 svn:date V 27 1998-12-24T12:07:16.000000Z K 7 svn:log V 340 Restored rev.1.31 which was clobbered by rev.1.69 (the big Lite2 merge). This fixes at least hanging in revoke(2) when a somewhat active slave pty is revoked. The hang made the window for the null pointer bug in ufsspec_{read,write} much larger. There are many other bugs in this area (revoke of an active fifo at best leaks memory...). END
