# strace -p 2475

produces lots of...
nanosleep({0, 0}, 0x7fff9b9b6060)       = 0
select(4, [3], [], [3], {0, 0})         = 0 (Timeout)
recvmsg(3, 0x7fff9b9b5df0, 0)           = -1 EAGAIN (Resource 
temporarily unavailable)
select(4, [3], [], [3], {0, 0})         = 0 (Timeout)
nanosleep({0, 0}, 0x7fff9b9b6060)       = 0
select(4, [3], [], [3], {0, 0})         = 0 (Timeout)
recvmsg(3, 0x7fff9b9b5df0, 0)           = -1 EAGAIN (Resource 
temporarily unavailable)
select(4, [3], [], [3], {0, 0})         = 0 (Timeout)
^Cnanosleep({0, 0}, Process 2475 detached
  <detached ...>

... before my packages are loaded as well as after the freeze. Identical 
AFAICT.
alt-. is not processed after the freeze.
