>Description:
when nescape-404/linux is run under the linux emulator libs
v. 2.4 it won't exit cleanly when a ^C is sent to it.
kdump has this to say about it:
7860 netscape PSIG SIGALRM caught handler=0x83c3980 mask=0x828d400 code=0x0
7860 netscape CALL sigreturn(0x861d3b4)
7860 netscape RET sigreturn JUSTRETURN
7860 netscape PSIG SIGALRM caught handler=0x83c3980 mask=0x828d400 code=0x0
7860 netscape CALL sigreturn(0x861d3b4)
7860 netscape RET sigreturn JUSTRETURN
7860 netscape PSIG SIGALRM caught handler=0x83c3980 mask=0x828d400 code=0x0
7860 netscape CALL sigreturn(0x861d3b4)
7860 netscape RET sigreturn JUSTRETURN
7860 netscape PSIG SIGALRM caught handler=0x83c3980 mask=0x828d400 code=0x0
7860 netscape CALL sigreturn(0x861d3b4)
7860 netscape PSIG SIGUSR1 SIG_DFL
At first glance it appears to be some sort of disagreement as to whether
SIGALARM resets itself or not.
