os/package.scala can throw a Fatal exception #24
Description
Specifically
val pwd: Path = os.Path(new java.io.File("").getCanonicalPath)
This can fail by:
: java.lang.ExceptionInInitializerError: null

Context: I was trying to us os.proc.call(), wrapped in a Try { } block in case it failed. Much to my surprise, this process died in prod with an exception that is excluded from NonFatal(), due apparently to os.File's constructor not liking the return value from new java.io.File("").getCanonicalPath apparently.
I see you addressed a similar issue here:
com-lihaoyi/Ammonite#376
Ultimately, i expect that Path's constructor should not be throwing like this, so should probably be less sensitive to the underlying FS implementation perhaps?
This is with version 0.2.9 for scala 2.11
