Ah, ok... Thanks. The reason I am asking is that I got jdk semi-working
but javac gets stuck in an infinite loop when compiling too many
files together. (sa_stacks-> timer_settime -> gettimeofday -> select
-> sa_stacks). This behavior changes when I change the stacksize
of the lwp's from 1<<18 to 1<<20 (javac gets a segmentation fault).
Unfortunately gdb does not work properly with threads and ktrace
is pretty much useless since I cannot even tell what thread i am
running. Since this patch is so intrusive and it seems to me that
the consensus is that it is the right way to go, we might as well
apply it and fix what breaks, because it is very difficult to keep
a 70000 line diff in sync.
