OK, I did some more digging. The freeze always happens when trying to read
several files from curlftpfs in one "operation" (cp, cat etc.). It freezes
on the last file. I did strace on curlftpfs and here's tail of the log:
recvfrom(6, "\32\235.\303\330\240d\25\26\241^*\305!\\!\27]]\203p\264"...,
16384, MSG_NOSIGNAL, NULL, NULL) = 1448
select(7, [6], [], [], {1, 0}) = 1 (in [6], left {1, 0})
poll([{fd=6, events=POLLIN, revents=POLLIN}], 1, 0) = 1
recvfrom(6, "\367\345\361\323UE\241\220N\343\312\367\'\23\200\203\333"...,
16384 , MSG_NOSIGNAL, NULL, NULL) = 1448
select(7, [6], [], [], {1, 0}) = 1 (in [6], left {1, 0})
poll([{fd=6, events=POLLIN, revents=POLLIN}], 1, 0) = 1
recvfrom(6, "\370\nnc\363\6,_\300\344\344a\341\304\241\214\\\20\240"..., 16384,

select(7, [6], [], [], {1, 0}) = 1 (in [6], left {1, 0})
poll([{fd=6, events=POLLIN, revents=POLLIN}], 1, 0) = 1
recvfrom(6, "", 16384, MSG_NOSIGNAL, NULL, NULL) = 0
close(6) = 0
poll([{fd=4, events=POLLIN, revents=POLLIN}], 1, 1000) = 1
recvfrom(4, "226 Transfer complete.\r\n", 16384, MSG_NOSIGNAL, NULL, NULL) = 24

Here curlftpfs was terminated.
Hope this hepls.
