Actually, they are doing nothing but waiting for a lock file to vanish:

open("/tmp/.mcr_cache_v78/.deploy_lock.6677801",
O_WRONLY|O_CREAT|O_EXCL, 0777) = -1 EACCES (Permission denied)
stat("/tmp/.mcr_cache_v78", {st_mode=S_IFDIR|0755, st_size=89, ...}) = 0

open("/tmp/.mcr_cache_v78/.deploy_lock.6677802", O_RDONLY) = -1 ENOENT
(No such file or directory)
stat("/tmp/.mcr_cache_v78", {st_mode=S_IFDIR|0755, st_size=89, ...}) = 0

nanosleep({0, 10000000}, NULL)          = 0

open("/tmp/.mcr_cache_v78/.deploy_lock.6677802",
O_WRONLY|O_CREAT|O_EXCL, 0777) = -1 EACCES (Permission denied)
stat("/tmp/.mcr_cache_v78", {st_mode=S_IFDIR|0755, st_size=89, ...}) = 0

open("/tmp/.mcr_cache_v78/.deploy_lock.6677803", O_RDONLY) = -1 ENOENT
(No such file or directory)
stat("/tmp/.mcr_cache_v78", {st_mode=S_IFDIR|0755, st_size=89, ...}) = 0

nanosleep({0, 10000000}, NULL)          = 0


The problem is (this is n0703) the directory belongs to jveitch and I
don't have any idea why your jobs want to open something in there.

I think I'll ask Keith Thorne about that, because I fear that deeper
Matlab knowledge is needed here.
