There is/was a patch for this, I don't recall what number...someone else...
and most likely Sun have rolled this into 4.1.3_U1 (don't you wish they
would roll a 4.1.4 and just be done with it ?  And move all those damn
security fixes that have gone into Solaris2 into SunOS 4 - some of us
_hate_ svr4 and the new kernel architecture - not very easy to customize
or configure/optimize the kernel at all!).

And there was a similar bug in Solaris2.x (x=0,1 ?) which has also been
patched.

ob`bug': ever had a cd-rom mounted on sunos4 and ejected it without
         umounting it first ? not much fun...
