Mc hangs after exit

[tempread]

On some FreeBSD servers i have sometimes bug: when i try to exit from mc it hangs. More detail:
1.run mc, press F10, press Enter - hangs
2.run mc, press F10, choose Command->File->Exit - NOT hangs.

When i remove /tmp/mc-root(i have many mc.pipe files there) problem disappear.

After some experiments i found how i can repeat problem at any server:
=====
run mc, remove contents of /tmp/mc-root(using started mc),exit from mc.
And:
run mc, press F10,press Enter - hangs
=====

Done.

Does mc hang up with disabled subshell support (mc -u)?
