[Ecls-list] gc hang after gc stats collection

[marc daya]

Greetings all,

I've run into a problem that appears to be related to the Boehm-Weiser
garbage collector.  On my (Gentoo) Linux system (gc t) simply hangs
after a (gc-stats t) call.  Without a (gc-stats t) call, repeated
calls to (gc t) seem to work fine (they return control to the REPL),
but the first (gc t) after a (gc-stats t) never comes back...

  #<"SI" package>
  SI> (gc-stats t)
  1
  1
  NIL
  SI> (gc t)

I traced it to this sequence after I found that 'time' appeared to simply hang.

This seems to work just fine on Windows though...  and both the Windows
and the Linux versions have been compiled using the default
Boehm-Weiser setting (included).
Does anyone else see this, or is it possible that its something that
is related to my system?
