I'm running libc-5.4.33, and netscape has been unusable since the late
.80's :-(. Worse yet, it has resisted all my efforts at stracing from a
cold start. If attach the program when it's running, the Heisenberg
Uncertainty Principle takes effect and, while sluggish at redraws, it
refuses to freeze.

It does lots and lots of this, though:

sigreturn() = ? (mask now [])
gettimeofday({891646637, 643327}, NULL) = 0
gettimeofday({891646637, 643771}, NULL) = 0
sigprocmask(SIG_BLOCK, NULL, []) = 0
gettimeofday({891646637, 644724}, NULL) = 0
sigprocmask(SIG_SETMASK, [], NULL) = 0
gettimeofday({891646637, 645751}, NULL) = 0
gettimeofday({891646637, 646269}, NULL) = 0
ioctl(9, FIONREAD, [0]) = 0
write(9, "\2\0\4\0c\4\200\2\0@\0\0\0\0\0\0"..., 16) = 16
--- SIGALRM (Alarm clock) ---

Maybe 100-200 gettimeofday() calls every time it is deiconified. When
idle it's:

oldselect(23, [6 7 9 10 22], NULL, [6], {182, 916298}

If anyone has a suggestion for getting it to start under strace, let me
know. This is getting frustrating.
