The ~ symbols are C braindamage. Ignore them, also the leading
_ on C externals. The double calls to mch$trap/mch$call indicate a
fault in kernel mode; the handler goes through them to prf$panic. The
rl$rlread calling lp$lpclose indicates gross lossage; investiaget
there for bugs. The problem with the system wedging is probably
buffer starvation; the system takes one block buffer for each mounted
FS and when you get a lot of FS's mounted the size of the buffer-pool
is appreciably smaller, leading to deadlocks. If any of this was
unbearably terse, let me know and I'll explain at length.
